Answer:
The correct answer will be option- D.
Explanation:
Neurons are the cells which help in the transmission of the signals to and fro from the CNS and PNS to the body and vice versa. The structure of the neurons is divided into three main parts: the axon, dendrites and the cell body. The dendrites and axons are the extensions of the cell cytoplasm and together constitutes the neurites.
The dendrites are the extensions of the cytoplasm which receives the signals either from the cell surface as well as the from the post-synaptic neurons and further process the signals.
Thus, option- D is the correct answer.
Heterotrophs are consumers, cannot make their own foods, and have some of them have the capacity to consume autotrophs. Hence, they are not at the base of most food webs.
Heterotrophs are organisms that have no capacity to manufacture their own foods, unlike autotrophs.
They depend on other organisms for their foods. Hence, they are known as consumers, unlike autotrophs that are called producers.
Heterotrophs are of different types:
- Herbivores: those that consume autotrophs only
- Carnivores: those that consume meat only
- Omnivores: those that consume both autotrophs and meat.
Thus, heterotrophs do not occupy the base of food webs. The base of food webs are mostly occupied by autotrophs, the producers.
