Ecosystems prior knowledge

biodiversity

Different animals

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

Biotic characteristics of an ecosystem

Competition

Predation

symbiosis

cellular respiration

The energy cycle

Living and non living things

Biotic

The living parts of an ecosystem

Abiotic

The non-living parts of an ecosystem

Abiotic Characteristics Ecosystem

Soil

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

Nutrients

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

Light

Plants and other organisms such as algae need light for photosynthesis

Oxygen

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

Water

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

roles within an ecosystem

entomophilous

animals that pollinate plants

bees

prey

birds

fish

mice

the animal that's being hunted/eaten

predator

animals that hunt other animals

wolves

Energy?

the sun

Types

grassland

tundra

freshwater

marine

biotic: -fish -plants -turtles -invertebrates -vertebrates -mammals -reptiles -amphibians -worms -coral -plankton

abiotic: -water -rocks -sand

desert

forest ecosystem

food chains

Every animal has a role

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

one animal eats another and it keeps going like a chain

Food web

A food web a system of interlocking and interdependent food chains

What is a ecosystem?

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

Human impacts

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.

Climate change

change in the climate or area from green house gases

Invasive species

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

Carrying capacity

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

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

Symbiotic relationship

A mutualistic relationship but both organisms need each other to survive

Commensalism

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

Mutualism

both species benefit from the relationship.

Sustainability

Healthy enviroment

Helping the enviroment

Stewardship

Caring about the enviroment

Responsibility

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

Eutrophication

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

phosphorus cycle

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.

Nitrogen cycle

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.

Organisms of the ecosystem

Decomposers

Organisms that break down detritus and releases nutrients

Detritus

Waste from dead remains from plants and animals

Producers

Makes its own food

Consumers

Eats plants and animals

Omnivores

Animals that eat both plants and animals

Carnivores

Animals that eat other animals

Herbivores

Animals that eat plants

Trophic levels

Trophic levels include primary producers and consumers

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

Tropic efficiency

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