Answer: A
Explanation:
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.
Heterotrophs are organisms that must consume food from other organisms because they are unable to synthesize their own food molecules.
<h3>What is heterotrophs?</h3>
- An organism is referred to be a heterotroph if it is unable to manufacture food on its own and must obtain it from other sources of organic carbon, primarily plant or animal materials.
- Heterotrophs are primary, secondary, and tertiary consumers in the food chain but not producers.
- Because they eat producers or other consumers, heterotrophs are referred to as consumers.
- Humans, dogs, and birds are all instances of heterotrophs.
- In a food chain, a group of creatures that supply energy and nutrients to other organisms, heterotrophs occupy the second and third levels.
- An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy.
- Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition."
- Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients.

Answer:
Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.
Explanation:
The large volumes of hyphae within the mycelium perform a fundamental role by obtaining nutrients from the organic substrates from the surrounding of the fungus. Hyphae play different kinds of functions in fungi.
They contain cytoplasm or cell sap. They also contain the nuclei, which include genetic material. Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.
The thallus is the fungus body in which the fungi live or from beneath the soil to give support to the fungi for its growth and its survival.

Explanation:
For the spread of disease, there is usually a host who bears the infectious agent, the agent exits through a port of exit from the host, is carried by a mode of transmission, then enters a susceptible second host through a port of entry. To stop transmission, stopping the infectious agent can include;
- Stopping the agent from leaving the host through port of exit – e.g quarantine the patient
- Curtailing the modes of transmission – e.g killing disease vectors
- Protecting the ports of entry in the susceptible second potential host – e.g by improving immunity
