They are competing for a biotic factor.

This is a predation.
There are 12 cows and 5 pigs lying down. Name the what type of ecosystem organization this is.
This is a community.
List three abiotic resources living things need.
They need air, water, and sunlight
In this food web, the grass and tree are the producers. What will happen if all the grass and trees burn away from this ecosystem?
All the other animals’ populations will go down, or they will migrate away.
They compete for a total of 4 factors.
A bird makes a nest in a tree. Name what type of symbiosis this is.
This is commensalism.
Two lions lay in their natural habitat. There is plenty of water to drink in the near by pond. Name what type of ecosystem organization this is.

A small pond is limiting how much organisms can get water and survive. Name what type of factor this is.

The definition of a niche.
An organism’s role in the ecosystem
Three populations eat a type of prey. A new population is introduced to this ecosystem, and they also eat this prey. What will happen to the prey and the three original populations?
The prey’s population will go down because it has too many predators, and the three original populations will go down because there is more animals to compete for the prey.

This is an example of a food chain: A plant, a caterpillar, a robin, and a hawk. Name what each organisms niche is in this food chain.
The plant is a producer, the caterpillar is a primary consumer, the robin is a secondary consumer, and a hawk is a tertiary consumer.
Two populations have the same niche in their ecosystem. They both eat the same food and share the same space. Name three things that could happen to these populations.
There could be competition, lower populations, and one of the populations could move out to find more food and space.
