Why is a mushroom considered a heterotroph?
A
It creates different types of food.
B
It makes food through photosynthesis.
C
It makes food through chemosynthesis
D
It obtains nutrients from its environment
Explanation: 

Detailed explanation-1: -Mushrooms are heterotrophs (i.e., they cannot perform photosynthesis). Consequently, they feed on organic matter. Chemical energy and useful materials are obtained from the digestion of substrates. Fungi are versatile in producing lytic enzymes active on many types of chemical bonds.

Detailed explanation-2: -Fungi are heterotrophic. They get their nutrition by absorbing organic compounds from the environment. Fungi, along with bacteria that are found in soil, are the primary decomposers of organic matter in terrestrial ecosystems.

Detailed explanation-3: -Final answer: Mushrooms get their food from dead and decaying plants.

Detailed explanation-4: -Saprophytic nutrition is the mode of nutrition in mushrooms. Organisms that die and decay organic matter are used as food in saprophytic nutrition. This process uses components contained in dead and decaying material for cellular needs.

Detailed explanation-5: -Fungi are heterotrophs, which means that they obtain their “food” from outside of themselves. In other words, they must “eat” their food like animals do. But they don’t really eat. Instead, they absorb their nutrients.
