Why are there always more producers than consumers in a food chain?

2 answers:

<span>Because for example one large eagle needs lots of small sparrows to eat. There is usually a food pyramid so for example you could display it along the lines of 1,000 worms are eaten by 20 sparrows which are eaten by 1 eagle. Its just the way things are. It is a fine balance. if you went up to two eagles on same land they would run out of food quickly and then would either starve or have to move on and using up all the food doesnt help them so it needs to be in a fine balance. A balanced ecosystem.</span>

At the base of each food chain, there are producers, namely autotrophic organisms, ie capable of organizing the chemical compounds in the soil (or water), so as to independently produce food reserves (sugars, starch). This process can be achieved by using the energy provided by photosynthesis. The producers are the only living things that can convert solar energy (light energy + thermal energy) into chemical energy (binding energy).

Complete question:

Which correctly describes the set of clades that contain the arthropods, from largest to smallest?

Archaea: Eukaryotes: Opisthokonts: Animals: Protostomes Ecdysozoa: Arthropods
Eukaryotes: Opisthokonts: Nuclearia: Animals: Protostomes Ecdysozoa: Arthropods
Eukaryotes: Opisthokonts: Animals: Deuterostomes Ecdysozoa: Arthropods
Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods

Answer:

4. Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods

Explanation:

Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.

The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually.

Animalia Kingdom: Includes different phyla closely relates.

The embryonary development of bilateral coelom animals makes a place for the division of two groups: protostomes and deuterostomes. Among protostomes might be mentioned the flatworms, annelids, mollusks, and arthropods. Protostomes show spiral initial segmentation, and the mouth develops as a first opening near the blastopore.

Ecdysozoan Superphylum: Their bodies are covered by a cuticle that provides protection. They have a complete digestive system. They might reproduce sexually and asexually.
Phylum Arthropoda: Invertebrates characterized for having an exoskeleton, a segmented body, and articulated appendixes. A very diverse group with many different characteristics.

a pollutant released on one continent is found concentrated in the tissues of organisms on another continent. Is this likely an

Neporo4naja [7]

Answer:

It is most likely an air and water pollutant.

Explanation:

The continents are separated with water and air. Therefore, if a pollutant is released from one continent, it could have transported to the other continent via water and air. Although the effect of air is less due to dispersing of air masses, it still have a chance to transport the pollutant at far distance. This phenomenon can also be related with the <u>transboundary pollution</u> where a pollutant travels to another place. For example, many persistent organic pollutants have beend detected in the bodies of polar bears living in arctic.

The liver acts to keep blood glucose at a relatively constant level. It takes up glucose from the blood when levels are too high

postnew [5]

Yes, these actions are an example of homeostasis. To fully understand this question you need to know the basic concept of homeostasis. Homeostasis is the body's regulation. What do I mean by that? It's simple, when you have a fever your body's temperature can skyrocket to 100 or more, when you start to sweat or get the chills that's your body's way to cool you down and fight the infection. Another example; when you do any physical activity, you sweat from it depending on the intensity. If you didn't sweat you would probably overheat and that would lead to other complications. Basically when you do exercise you sweat because your body is warm and that's the homeostasis mechanism that helps cool down your body bring it to it's normal temperature. So in end answering your question in more detail by the liver regulating the body by taking glucose in when levels are too high or adding glucose in when levels are too low is an example of homeostasis because the body is regulating itself to come back to it's normal healthy function state.

Hope this helped :)
