Answer: A niche refers to the ecological role of organisms in its community.
Example snake.
Three niches of snake are:
1. Predators- they can act as pests control in the field (one of their sources of food is rats)
2. Prey- they can also be a source of food to other higher ranking species in the food web such as the eagle.
3. Contribute to the balance of the food web.
What question I can’t see them or you never put them down
Im pretty sure the answer is elk, since they were eaten by the wolves in the rocky mountains.
<span>The answer is cell wall. It is the rigid outer layer
of plant cells that is composed of subunits of cellulose molecules,
pectin, lignin, or hemicellulose. It enables
the plant to withstand turgor pressure,
without bursting, required to give them support.</span>
The main factor that determines a populations growth rate is the availability of resources. Other factors can contribute, such as competition for food, disease, weather, immigration/emigration, birth/death rate, etc.
