Question

carbon dioxide, in the atmosphere
Answer the following questions.
1. Distinguish between-
(a) autotrophs and heterotrophs
(b) decomposers and scavengers​

Answer 1

Answer:

(a) Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it.

(b) The main difference between scavenger and decomposer is that scavenger consumes dead plants, animals or carrion to break down the organic materials into small particles whereas decomposer consumes the small particles produced by the scavengers. Scavengers can be animals such as birds, crabs, insects, and worms.
