These are government created areas where hunting and fishing by humans are not allowed.

Identify the parasite in this food web. Are parasites healthy for their hosts?
The tick is the parasite. Parasites can be unhealthy or harmful for their hosts because they can carry diseases or viruses.
500
Why is extinction of a species significant?
When a species becomes extinct, it is no longer present in its ecosystem, which can disrupt the food chain. It also results in less biodiversity.
