Ecosystems & Biomes
This includes all the living and nonliving things in an area.
ecosystem
A group of the same species living in one area is called this.
population
The natural home of an organism is called this.
habitat
In this relationship, both organisms benefit.
mutualism
Sunlight is an example of this type of environmental factor.
abiotic factor
This is a large region with similar climate and organisms.
biome
All the different populations living together make up this.
community
This term describes the role or job of an organism in its environment.
niche
In this relationship, one organism benefits and the other is harmed.
parasitism
Trees are an example of this type of factor.
biotic factor
These are the nonliving parts of the environment.
abiotic factors
This term means the number of organisms living in a certain area.
population density
Food shortages and predators are examples of this type of factor.
limiting factor
In this relationship, one organism benefits while the other is unaffected.
commensalism
When resources run low because too many organisms live in one area, this occurs.
overpopulation
Plants, animals, and bacteria are examples of these factors.
biotic factors
When a population grows too large, this increases because resources become limited.
competition
This is the largest possible population size under ideal conditions.
biotic potential
A tick living on a dog is an example of this relationship.
parasitism
The correct order from smallest to largest is population, community, and this.
ecosystem
This describes gradual changes in an ecosystem over time.
succession
This is the maximum population size an environment can support.
carrying capacity
A desert cactus surviving with little water is an example of adapting to this type of factor.
abiotic factor
Bees pollinating flowers is an example of this relationship.
mutualism
This happens when organisms compete for limited food, water, or space.
