1. How many food chains make up the food web?

viva [34]

Answer:

A food web can be formed by more than one food chain, since the webs includes all possible interactions that can occur between individuals of different trophic levels.

Explanation:

Based on the scheme shown in the image

<h3>1. How many food chains make up the food web? </h3>

This food network is made up of three food chains

<em>Plant → Bird → Snake</em>
<em>Plant → Insect → Bird → Snake</em>
<em>Plant → insect → Frog → Snake</em>

Food webs often include several food chains, since they are due to the interaction between organisms at different trophic levels, which actually happens within an ecosystem.

<h3> 2. Which organism is an herbivore? </h3>

In this case, both the insect and the bird are herbivorous organisms, since they feed of the producer, which is the plant.

<h3> 3. Which organism is an autotroph? </h3>

The only autotrophic organism is the plant, since it is capable of manufacturing its nutrients from sunlight and inorganic matter.

<h3> 4. Which organism is a third-order heterotroph? To what trophic level does that organism belong? </h3>

The third order heterotroph is the snake, since it feeds on other animals. The snake is a carnivore and can be a secondary or more commonly tertiary consumer, so it can be placed in the 3rd or 4th trophic level.

<h3> 5. Which organism is an omnivore? </h3>

According to the scheme proposed, the bird is omnivorous, since it feeds on both plants and insects.

<h3> 6. Which organisms belong to more than one food chain? </h3>

In this case, the plant, the insect, the bird and the snake are part of more than one food chain.

<u><em>Plant → Bird → Snake</em></u>
<u><em>Plant → Insect → Bird → Snake</em></u>
<u><em>Plant → insect</em></u><em> → Frog → </em><u><em>Snake</em></u>

<h3> 7. Which organism belongs to more than one trophic level? </h3>

The bird can be located in both the second and third trophic level, being a primary consumer —when it feeds on plants— or secondary, when it feeds on insects.

<h3> 8. What are decomposers? From which trophic levels are the organisms that decomposers feed on? </h3>

Decomposers are generally bacteria and fungi, organisms capable of degrading organic matter, thus enriching the soil. Decomposers can feed on any trophic level.

<h3> 9. What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain? </h3>

As the ascent of the pyramid occurs —or at the upper trophic level— the amount of energy available decreases. This is because from one trophic level to another only 10% of the energy can be used. If a plant has 5000 Kcal available, the herbivore that consumes it can only use 500 Kcal.

<h3> 10. Why do different trophic levels have different amounts of energy?</h3>

The main <u>reason for the difference in energy in each trophic level is that energy is lost in each one of them</u>, which the organisms use in their metabolism. A consequence of the metabolism is the loss of energy as heat, which is acquired by the environment.

What are the chararistics meoisis include

vlada-n [284]

Meiosis is a kind of cell division.
it's used to reduce half of the chromosomes and prodouce 4 gamete cells, which we call these cells haploid.
for example, it is used in human reproduction, for the sperm and ovum, in order to have a sexual reproduction.
the offspring of them are genetically non identical to the parent.

If mitosis stopped in your body, what effects would you see most rapidly? Which tissues would

kogti [31]

Cell division during mitosis is necessary for replacing damaged or dying cells, as well as repairing damaged or worn-out cells that occur naturally. The main mechanism behind growth is this kind of cell division.

<h3>What are the consequences if mitosis stopped in the body?</h3>

Without mitosis, there wouldn't be any cell division or growth. The fact that genetic information cannot be passed on is most essential. All cell processes would be significantly impacted.

You might also suffer serious consequences, as your heart would have to beat by itself, among other things. Your bones or your brain wouldn't be immediately impacted, but your blood cells would.

Therefore, Every cell in your body would stop replicating itself if mitosis halted, which would induce a heart attack.

Is the vagus nerve the heart rate centre of the brain?

koban [17]

Answer:

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.

Explanation:

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.

There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts

The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:

-Sensory: From the throat, heart, lungs, and abdomen.

-Special sensory: Provides taste sensation behind the tongue.

-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.

-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.
