Commensalism

When members of two species interact and one benefits while the other is not effected.

Mutualism

When two species interact and they both benefit

Parasitism

One specie benefits at the expense of another organism

Competition within species

when two members of the same specie compete for the same resource

Predation

When one organism kills and eat the other

Competition between species

when two individuals of different species compete for the same resource

Adaptations

Adaptations are features that an organism has to help it survive

Structural Adaptations (touch or draw it)

Physical features

Behavioral Adaptations

How an organism behaves

Functional Adaptations

How an organism functions

Endotherms

Generate own heat from within their body

Ectotherms

Have to get their heat from the environment

Food Chain

Representation of the flow of energy in an ecosystem

Ecology

The study of the interactions between plants, animals and the environment in which they live in.

Ecosystem

System formed by a group of living things that interact with each other and their non-living surroundings

Sunlight

Energy from the sun needed for photosynthesis

Photosynthesis

The process where plants produce their own food in the form of glucose

Consumer/Heterotroph

Living things that can’t photosynthesize

Producer/autotroph

Organisms that can photosynthesize

Biotic

Was/is living

Abiotic

Never living

Decomposer

Organisms that obtain their nutrients by breaking down the dead bodies of other organism and returning nutrients to the soil

Detritivore

An animal that feeds on dead organic matter. (EAT ORGAINC MATTER)

Habitat

Where an organism lives at a given time

Environment

All the factors in an organism’s surrounding that effect the organism

Population

All of the individuals of one species that live in the one habitat

Community

All of the living organisms in an ecosystem

10% RULE

10% of the energy from one trophic level is passed to the next trophic level. The other 90% is used by the organism in its daily life

Biodiversity

Considers both the number of species present and the relative abundance of the specie

ecosystems with high species diversity …. ……. ……….. …..

have greater conservation value

Species richness

refers to the number of species in an ecosystem regardless of the abundance
