Grade 9 Biology Unit

Living things in an ecosystem are considered to be:

• abiotic

• biotic

• producers

• decomposer

This is the process of food making done by producers like plants.

• cellular respiration

• succession

• photosynthesis

• trophic efficiency

Tags

NGSS.MS-LS1-6

This is the trapping of heat by gases in Earth's atmosphere.

• trophic efficiency

• acid precipitation

• bioaccumulation

• greenhouse effect

Tags

NGSS.HS-ESS2-4

NGSS.HS-ESS3-5

These are species that are not native to an area, but do well and become established there

• alien species

• invasive species

• dominant species

• keystone species

Tags

NGSS.MS-LS2-5

This is the build-up of algae in the water because of the phosphorus in the extra fertilizer that drains in.

• urban sprawl

• fermentation

• eutrophication

• deforestation

NGSS.MS-LS2-4

NGSS.MS-LS2-5

This relationship involves one species benefitting while harming the other one negatively

• mutualism

• commensalism

• parasitism

• symbiosis

Tags

NGSS.MS-LS2-4

These species are the most abundant in an ecosystem.

• dominant species

• keystone species

• alien species

• invasive species

This is each phase in food chains; can include producers, primary consumers, and apex predators.

• sustainable ecosystem

• limiting factors

• succession

• trophic level

Tags

NGSS.MS-LS2-3

This is the position or special job/service that an organism has in an ecosystem

• limiting factors

• biotic

• ecological niche

• biodiversity

Beavers are an example of this; an organism that helps to alter an ecosystem

• ecosystem engineer

• invasive species

• parasitism

• bioaccumulation
