Question

Q18. Differentiate the following:-

b) Autotrophs and Heterotrophs.
c) Arteries and veins.​

Answer 1

Answer:

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. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.

Answer 2

Answer:

Autotrophs --

1)Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs make their "food" through photosynthesis using the energy of the sun.

2) An autotroph is an organism that can synthesize their organic molecules from simple inorganic substances. They are producers.

Heterotrophs --

1) Heterotrophs cannot make their own food, so they must eat or absorb.

2) A heterotroph is a consumer and it obtains organic molecules from other organisms.
