What is the limiting factor for the deer?
What is food?

What is abiotic?

What is a biome?
A relationship where one organism benefits and the other is harmed?
What is parasitism?

On the floor of a thick jungle, the soil is perfect and there is tons of rain. However, the tiny plants on the ground are not growing. High above them, giant trees have huge leaves that cover the sky.
What is the limiting factor for the tiny plants?
What is sunlight?

What is a biotic factor?
A community of living organisms interacting with one another and their non living environment.
What is an ecosystem?
What is a relationship where one organism benefits and the other is neither helped or harmed?
What is commensalism?
How can disease limit a population?
What is the disease can cause organisms to die or reproduce less?
In the desert, it is very sunny (great for plants!) and there is lots of sand for roots to grow in. But it only rains once a year.
What is the limiting factor that keeps a desert from becoming a lush green forest?
What is water?

What is a predator?

What is mutualism?

In a clear stream, a group of green algae is trying to grow. There is plenty of cool water and many fish swimming around, but a large bridge has been built over the stream, casting a dark shadow all day. The algae stops growing.
What is the limiting factor? * Is it Biotic or Abiotic?
What is abiotic and sunlight?
An animal that is hunted by other animals and eaten?
What is prey?
All organisms in an area that belong to the same species.
What is a population?
Cattle egrets follow cows and eat insects stirred up by their movement. The cows are unaffected. What type of symbiosis is this?
What is commensalism?
What recycles nutrients back into the soil so producers can use them?
What are decomposers?
A family of owls lives in a barn. There are plenty of places to nest and the weather is perfect. However, a group of outdoor cats moved into the area and ate all the field mice that the owls usually hunt.
What is the limiting factor? Is it Biotic or Abiotic?
What is biotic and it is mice (food)?
The maximum size that a population can reach in an ecosystem?
What is Carrying Capacity?
An individual living thing.
