Question

All animals and fungi are autotrophs
A. True
B. False

Answer 1

Hint: Autotrophs are organisms that can make their own food from inorganic substances. The word root of autotroph means auto means self and troph means nourishment. They are also known as primary producers.

Complete Answer:
1. Autotrophs: Plants and algae are generally autotrophs which means they make their own food. They produce organic compounds (such as glucose, proteins) from inorganic substances (such as carbon dioxide). Their source of energy is sunlight to create fuel molecules.
2. Heterotrophs: All Animals are heterotrophs which means that they can't make their own food and consume organic matter which is produced by the autotrophs. They are also known as consumers. Along with the animals ,all fungi, some protists , some bacteria, are heterotrophs. Consumers are typically viewed as predatory animals such as meat eaters. However, herbivorous animals and parasitic fungi are also consumers
- Option A is incorrect because all animals and fungi are not autotrophs.
- Option B is correct because all animals and fungi are heterotrophs as they can't produce their own food. They all depend on the autotrophs( primary producers) and on other organisms for food. Hence, also known as consumers. Heterotrophs obtain their energy by breaking down carbohydrates or organic molecules obtained in food.

Thus, the correct option is B) False.

Note: Heterotrophs can be further divided into three,
1. Herbivores - These animals only feed on plants and grasses
2. Carnivores - These animals feed mainly on meat
3. Omnivores - These animals eat both grass and meat
