The number of organisms in a food pyramid decrease as the trophic level

Answers

Answer 1

Answer: Normally, the number of organisms in a food pyramid decreases as the trophic level increases. But in some cases, the pyramid may be inverted, for instance, when the productor is a single tree, and beetles eats its leaves, and birds eat the beetles. There is the biomass pyramid too, that represents the amount of mass present in the organisms of the food chain.

The reason tropical deforestatio is worse than temperate deforestation is because there is a. there is more carbon in the ground in temparate forests
b. more carbon in tress in temperate forests
c. rates of photosysnthesis are higher in temperate forests

Answers

Answer:

Option A, there is more carbon in the ground in temparate forests

Explanation:

In temperate forests the nutrients are mostly found in the soil including the carbon, while in case of tropical forests these nutrients (including carbon) are up taken by the trees and stored there itself. Now when the tropical forest trees are cut down the carbon reserves with in the trees is destroyed and released in the atmosphere. As per estimate the amount of carbon released by deforestation of tropical forest is much more disastrous than the gas emission of automobiles and industries in the current time.

Hence, option A is the correct choice of answer

How does animal bioenergetics help explain the net production pyramid?

Answers

Answer:

Animal bioenergetics is the study of how animals convert food into energy and biomass. The amount of energy that is converted into biomass is called the net production. The net production pyramid is a graphical representation of the amount of net production at each trophic level in an ecosystem.

There are two main factors that explain why the net production pyramid is shaped like a pyramid:

Trophic efficiency: Trophic efficiency is the percentage of energy that is transferred from one trophic level to the next. In most ecosystems, trophic efficiency is relatively low, typically ranging from 5% to 20%. This means that for every 100 units of energy that are produced by the primary producers, only 5 to 20 units of energy are available to the primary consumers.

Biomass loss: Not all of the energy that is converted into biomass is retained by the organism. Some of the energy is lost as heat, and some of it is used for metabolic processes such as respiration. As a result, the amount of biomass at each trophic level is always less than the amount of biomass at the previous trophic level.

The combination of these two factors results in the net production pyramid having a pyramidal shape. The primary producers have the most biomass, and the biomass decreases at each successive trophic level.

There are some exceptions to the shape of the net production pyramid. For example, in some ecosystems, the biomass of the primary consumers may be greater than the biomass of the primary producers. This can happen in ecosystems where the primary producers are small and short-lived, such as in a desert ecosystem.

The net production pyramid is a useful tool for understanding the flow of energy through an ecosystem. It can be used to track the amount of energy that is available to different organisms in the ecosystem, and it can help to identify the limiting factors that affect the productivity of the ecosystem.
