Zinaida [17]3 years ago
5 0

Answer:B. Sunlight provides energy to producers

Explanation: photoautotrophs (plants) produce energy from sunlight by photosynthesis. This is the only energy production based on an external source of energy. Plants, whether alive or dead, are consumed by heterotrophs - bacteria, fungi and animals. The nutrients and energy from dead heterotrophs (and some live ones) are recycled by both autotrophs and heterotrophs.

Ann [662]

The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.

In the ecosystem, the living and non-living things interact over time leading to exchange of energy.

A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.

The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).

The energy flow is indicated with an arrow thus,

grass ---> rabbit -----> wolves.

Food chain, therefore includes linear sequence of organisms.

Food web on the other hand illustrates a complex feeding relationship within the ecosystem.

The food web is made up of a prey that can be eaten by more than one predator.

Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.
