Question

Without plant food sources such as sugar, starch, and other carbohydrates there would still be mushrooms and algae, but there would be no fruits, vegetables, grains, or any animals. TRUE FALSE

Answer 1

True

Step-by-step explanation:

Algae are autotrophs and do not depend on plants for food and energy. Mushrooms are fungi that can derive their nutrition from dead and decaying bodies of algae in absence of plants and animals. So, both algae and mushrooms can survive in absence of plants.

Fruits, vegetables and grains are obtained from plants. If there would not by any plants, these plant products would not be available. Animals are heterotrophs and depend directly or indirectly on plants for food and energy. So, animals cannot sustain life without plants.

Hence, given statement is true.
