• A group of similar organisms that can breed and produce fertile offspring.

• The physical environment where organisms live, including soil, water, and air.

• A community of organisms interacting with each other in a specific habitat.

symbiosis

• a relationship in which two organisms live together and at least one benefits

• a competition between two species for resources

• a process where one organism consumes another

• a situation where organisms live in isolation

competition

• The struggle between organisms to survive as they attempt to use the same limited resources in the same place at the same time.

• A cooperative interaction between different species for mutual benefit.

• The process by which organisms adapt to their environment over generations.

• The phenomenon where organisms of different species live in the same habitat without interacting.

prey

characteristics

• features that make organisms different from one another

• common traits shared by all organisms

parasitism

• a symbiotic relationship in which one organism benefits while the other is harmed
