Science symbiosis and limiting factors

Predator

an animal eats another animal for energy and nutrients.

Prey

An animal that is eaten by a predator

Why do predators eat animals

To gain energy and nutrients

Camouflage

Helps predator or prey to blend in with its environment

How are the populations between predator and prey related

Predators rely on prey for food, so the sizes of predator and prey populations are linked together if one population grows or shrinks, the other one is affected

Symbiosis

A close, long-term relationship between different species in a community

Mutualism

A symbiotic relationship in which both organisms benefit

Commensalism

A symbiotic relationship in which one organism benefits, while the other is unaffected

Parasitism

A symbiotic relationship in which one organism benefits, and another is harmed

Parasite

The organism that benefits

Host

The organism that is harmed

In the natural work, competition means..

Competing for resources

five resources organisms compete for:

Food, water, sunlight, shelter and mates

Ecology

Is the study of how organisms interact with one another and with the environment

Biotic factor

A living part of the environment

Abiotic factor

A nonliving part of an environment

Six abiotic factor:

Water, nutrients, soil, sunlight, rainfall, or temperature

How are ecosystems different from communities

In an ecosystem, energy and other resources are exchanged between organisms and the environment. A community is made up above all the species that live and interact in an area. The species depends on each other for many things like shelter and food.

Habitat

The place where an organism usually lives

Limiting factor

An environmental factor that keeps a population from reaching its full potential size

9 limiting factors:

Food supply, water, shelter, living space, light, nutrients, predators, parasites and diseases

Native species

Our species that naturally live in an ecosystem

Nonnative species or introduced species

species that have been brought to an ecosystem by humans
