Answer:

See explanation below.

Explanation:

1. Explain the difference in the roles of producers, consumers, and decomposers in the Everglades.

In the Everglades, producers would be all species of organisms that are autotrophs such as different species of plants. Consumers are categorized into three: primary, secondary and terciary consumers. Primary consumers feed on plants (e.g. insects), secondary consumers eat the primary consumers (e.g. mice or rats), while tertiary consumers are higher predators that eat the secondary consumers (e.g. racoons). Finally, decomposers are bacteria, archaeans, fungi, or worms that live in soil which decompose organic matter.

2. Based on your knowledge of how to classify living organisms, in what domain and kingdom do the producers, consumers, and decomposers belong?

In Biology, the three domains are Archaea, Bacteria, and Eukarya; while there are six kingdoms: Archaebacteria, Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia.

Producers, that is plants, belong to the Domain Eukarya and the Kingdom Plantae.
Primary, secondary, and tertiary consumers also belong to the Domain Eukarya and to the Kingdom Animalia as they are all animals and eukaryotes.
Decomposers are classified into the three domains: Archaea, Bacteria, and Eukarya. Bacteria belong to the domain Bacteria, archaeans belong to the domain Archaea, and worms and fungi belong to the domain Eukarya. On the other hand, decomposers are classified into Archaebacteria, Eubacteria, Protista (oomycetes), Fungi, and Animalia (worms).

3. How did energy travel in the Everglades BEFORE the alligators were removed?

Aquatic plants (producers) <-- bass <-- bluegill <-- gar <-- alligator

Aquatic plants (producers) <-- zooplankton <-- bass/bluegill <-- wood stork <-- alligator

Plants (producers) <-- cattle <-- alligator

Plants (producers) <-- insects <-- rats <-- racoons <-- alligator

4. How did removing the alligators from the food web change how energy flowed in the Everglades?

Once the alligators were removed from the food web, the populations that were once in decline began to recover because of the lack of predators. Consequently, the lack of alligators led to the uncontrollable growth of racoons, wood stork, and gar, which could also cause an alteration as they consume ecologically and economically important fish species such as the bass and bluegill.

5. How did the problem begin, and what action(s) should Ranger Imani take to solve this issue?

The problem began when the populations of alligator, an apex predator that sits at the top of the food chain, grew at an accelerated pace. This led to the uncontrolled predation of other organisms that are also fundamental to maintain an ecological balance. Therefore, Ranger Imani decided to humanely euthanize the alligators, which were preying upon them. This led to a huge increase in wood stork, gar, and racoon populations.

Alligators should not be completely removed because they help to maintain an ecological balance. Instead, Ranger Imani should work on controlling populations by implementing Wildlife Population Management strategies, such as sustainable fishing, to prevent a certain species population from reaching a high number of individuals in order to keep a healthy ecosystem where all populations are stable because removing all apex predators is not the appropriate strategy as it significantly alters the ecosystem.

Explain Mercury is the planet closest to the Sun. Why does it get so cold at night?

alexdok [17]

Answer/Explanation: On Mercury temperatures can get as hot as 430 degrees Celsius during the day and as cold as -180 degrees Celsius at night.

Mercury is the planet in our solar system that sits closest to the sun. The distance between Mercury and the sun ranges from 46 million kilometers to 69.8 million kilometers. The earth sits at a comfy 150 million kilometers. This is one reason why it gets so hot on Mercury during the day.

The other reason is that Mercury has a very thin and unstable atmosphere. At a size about a third of the earth and with a mass (what we on earth see as ‘weight’) that is 0.05 times as much as the earth, Mercury just doesn’t have the gravity to keep gases trapped around it, creating an atmosphere. Due to the high temperature, solar winds, and the low gravity (about a third of earth’s gravity), gases keep escaping the planet, quite literally just blowing away.

Atmospheres can trap heat, that’s why it can still be nice and warm at night here on earth.

Mercury’s atmosphere is too thin, unstable and close to the sun to make any notable difference in the temperature.

Space is cold. Space is very cold. So cold in fact, that it can almost reach absolute zero, the point where molecules stop moving (and they always move). In space, the coldest temperature you can get is 2.7 Kelvin, about -270 degrees Celsius.

Sunlight reflected from other planets and moons, gases that move through space, the very thin atmosphere and the surface of Mercury itself are the main reasons that temperatures on Mercury don’t get lower than about -180 °C at night.

Which type of soil is the most permeable

Angelina_Jolie [31]

I believe the correct answer from the choices listed above is option B. It is sand that is the most permeable. It can be proved by the value of the Permeability variation where send has the highest value of 5.0. Hope this answers the question. Have a nice day.

Can you define these words?? Thanks!

Answer:

Cellulose - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.

Chlorophyll - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

Chloroplast - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.

Bryophyte - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

Pterophyte - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

Gymnosperm - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.

Cone - A cone-shaped flower head of various plants like banksias and proteas.

Angiosperm - Any flowering plant characterized by having ovules enclosed in an ovary and thus, produces fruits, as well as, seeds.

Flower - A reproductive structure in angiosperms and often conspicuously colorful and typically including sepals, petals, and either or both stamens and/or a pistil.

Cuticle - A noncellular protective covering outside the many invertebrates and plants.

Vascular tissue - The complex tissues that consist of various cell types and primarily responsible for transporting liquid and other nutrients throughout the plant or animal body.

Xylem - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.

Phloem - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.

Roots - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.

Root hairs - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

Stems - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.

Leaves - The green and flat organ that represents the most prominent feature of the most vegetative plants.

Photosynthesis - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).
