Topic 9- Ecosystems and Material Cycles Flashcards
Species is…
Organisms that can reproduce and produce fertile offsprings
Organisms are …
A living thing
Population …
A group of organisms that all belong to the same species
Community…
All the organisms that live in a particular habitat
Habitat…
Where an organism lives
Niche…
The role an organism has in its environment (where it lives, what it does, what it eats)
Ecosystem…
All the living things within a given area interacting with one another
Environment…
All living things and non living things (weather, rocks ect.) in a given area
Trophies level is…
A stage or level of animals/organisms in a food chain or web which an organism is feeding
Consumer is…
An organism which eats the pervious trophic level to gain energy
An organism which feeds on another organism
Trophic level one is…
An autotroph because it will make its own food
Order of food chain (eg.owl)
- Producer eg. Plant
- Herbivore/consumer eg. Insect
- Omnivore/consumer eg. Mouse
- Carnivore/consumer eg. Owl
A food chain…
Shows the path of energy from one living thing to another
Energy is lost each trophic level through…
Life processes, respiration (in mitochondria + include equation) used to transfer energy for movement, heat ect. which is not past onto the next trophic level
Energy stored as biomass which makes new cells to grow ect.
Also not all the organism may be consumed/eaten by the consumer
Not all the organism can be digested which becomes waste (faeces)
Biomass is…
The mass of living materials are that makes up an organism
Energy is stored in this material
