Ecosystems prior knowledge

A measure of the amount of energy or biomass
transferred from one trophic level to the next
higher level

A category of organisms that is
defined by how the organisms
gain their energy

Trophic levels include primary producers and consumers

Eats plants and animals

Animals that eat plants

Animals that eat other animals

Animals that eat both plants and animals

Makes its own food

Waste from dead remains from plants and animals

Organisms that break down detritus and releases nutrients

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into various chemical forms as it circulates among the atmosphere and terrestrial and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.

The phosphorus cycle is the slowest one of the matter cycles that are described here. Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts. Phosphate salts that are released from rocks through weathering usually dissolve in soil water and will be absorbed by plants.

A process in which nutrient levels in aquatic ecosystems increase, leading to an increase in the populations of primary producers

the job of supervising or taking care of something, such as an organization or property

Responsibility

Caring about the enviroment

Helping the enviroment

Healthy enviroment

both species benefit from the relationship.

one species beifits (obtains food or shelter) from the other species. Does not harm or help the other species.

A mutualistic relationship but both organisms need each other to survive

Is the largest population of a species that any ecosystem can support

When a population is maintained at its carrying capaticy the size of the population is at an equillibrium

non-native (or alien) to the ecosystem under consideration Doesnt belong in the certian ecosystem

change in the climate or area from green house gases

Humans have a big part on the ecosystem. Pollution is a big thing that we made that is making the earth worse. We also cut down trees were animals live.

An ecosystem is a biological community of interacting organisms and their physical environment.

A food web a system of interlocking and interdependent food chains

one animal eats another and it keeps going like a chain

If something new gets introduced into a certian food chain then the whole food chain can get messed up

Every animal has a role

abiotic:
-water
-rocks
-sand

biotic:
-fish
-plants
-turtles
-invertebrates
-vertebrates
-mammals
-reptiles
-amphibians

animals that hunt other animals

prey

the animal that's being hunted/eaten

mice

fish

birds

entomophilous

bees

animals that pollinate plants

All organisms need water to survive. Plants take up water through
their roots. Animals need water too

Many organisms, including plants and animals, need oxygen. Aquatic organisms get oxygen from water

Plants and other organisms such as algae need light for photosynthesis

All organisms need nutrients to grow. For example, plants and animals need nitrogen and phosphorus

Soil provides nutrients for plants and a habitat for many micro- organisms

The non-living parts of an ecosystem

The living parts of an ecosystem

Biodiversity is the variety of life in the world or in a particular habitat or ecosystem.

Different animals
