Ecosystem and Environment

Ecosystem

• An ecosystem consists of a community of living organisms (biotic) and their non-living (abiotic) factors.
• It is the interaction between living and non-living components that shape the ecosystem.

Environment

• The environment refers to all the living and non-living elements that affect an organism.
• It includes both biotic and abiotic factors that influence an organism's survival.

Habitat

• A habitat is a place where a population of organisms live.
• It is a specific environment that provides the necessary conditions for an organism to survive.

Biotic and Abiotic Factors

• Biotic factors are living organisms in an ecosystem.
• Abiotic factors are non-living components of an ecosystem, such as water, sunlight, and soil.

Community and Population

• A community is the different populations in the same habitat interacting with each other.
• A population is a group of organisms of the same species, living in the same habitat at the same time.

Species

• A species is a group of organisms that can reproduce with one another and create fertile offspring.

Interactions between Organisms

• Collaboration: when organisms cooperate with each other to ensure their survival.
• Mating: occurs between members of the same species to ensure their survival.
• Competition: when organisms use the same limited resource.
• Symbiosis: a close physical relationship between two organisms of different species.

Types of Symbiosis

• Mutualism: a relationship between two organisms in which they both benefit.
• Commensalism: a relationship between two organisms - one benefits, one is not affected.
• Parasitism: a relationship between two organisms - one lives in or on the body of another (parasite benefits), host is harmed.

Predation

• Predation: a relationship where one organism hunts, kills, and consumes another organism.
