Question

What statement describes the relationship between the deer and the bear and the food web?

Answer 1

Answer: a) Autotrophs supply food for the heterotrophs.

Explanation: Autotrophs are organisms that can produce their own food, while heterotrophs need to ingest its energy source.

Plants are autotrophs because, through photosynthesis, they can produce glucose and oxygen, a source of energy.

Deer is a heterotroph which feeds itself by eating plants. Bears are also heterotrophs who get their energy source through ingesting deers. So, in the food web, plants, who produce their own food, is the energy source of deer, which, in its turn, is the food source of a bear.

In conclusion, autotrophs are the primary food supply in the food web, supplying food for the heterotrophs.

Answer 2

The correct answer is B. Heterotrophs compete from the same food.

Deer is the autotrophs. This is because it gets food from the bear and that dear can make its own food. Bear is the heterotroph it cannot provide food for itself. 

It acts as a consumer to deer. Organisms which produces complex organic compounds for example fats, proteins, and carbohydrates from simple substances which are present in the surrounding, are autotrophs.
