Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is NOT a way that fungi obtain energy?
A
They secrete digestive juices onto a food source then absorb the dissolved food
B
They make their own food through photosynthesis
C
They decompose dead organisms
D
They live as parasites on a host organism
Explanation: 

Detailed explanation-1: -But fungi do not contain chlorophyll, the pigment that green plants use to make their own food with the energy of sunlight. Instead, fungi get all their nutrients from dead materials that they break down with special enzymes.

Detailed explanation-2: -Mushrooms aren’t plants because they don’t make their own food (plants use photosynthesis to make food). The underground part of the fungus uses enzymes to “digest” other substances that it can use as food.

Detailed explanation-3: -However, they are different from plants in two important ways: 1) fungi cell walls are composed of chitin rather than cellulose (plants) and 2) fungi do not make their own food like plants do through photosynthesis. They are eukaryotic. They get their food by decomposing matter or eating off their hosts as parasites.

Detailed explanation-4: -Fungi are consumers, and therefore they get the energy they require to survive from other creatures. There are three main ways fungi obtain energy: living in or on other animals as parasites, decomposition of dead organic matter, and living mutually with other creatures.

Detailed explanation-5: -Fungi are not capable of photosynthesis: They use complex organic compounds as sources of energy and carbon. Some fungal organisms multiply only asexually, whereas others undergo both asexual reproduction and sexual reproduction.
