Biology
Heterotrophs
Can not produce it's own food
Autotrophs
Can produce it's own food
Explain how carbon dioxide and oxygen are cycled through an ecosystem.
Carbon is removed from the atmosphere through photosynthesis while oxygen is released. Carbon is returned to the atmosphere through cellular respiration while oxygen uses cellular respiration to release water into the atmosphere.
Carbon is removed from the atmosphere through?
Carbon is removed through the atmosphere through PHOTOSYNTHESIS
Carbon is returned to the atmosphere through?
Carbon is returned to the atmosphere through CELLULAR RESPIRATION
Animals (consumers) can only preform what?
Cellular respiration
Denitrification
Convert nitrate and ammonia back into nitrogen
Ecological pyramids
Describe the energy flow and biomass among the trophies levels
Pyramid of energy
Shows amounts of energy passed on from level to level
Pyramid of biomass
Shows the total amount of living material available at each trophic level
Ecology
Study of the interactions among organisms and their environment
Trophic levels
The feeding levels of an organism
Niche
The function or job an organism preforms in it's habitat
Why is nutrient cycling important in the ecosystem?
To save the ecosystem
Give 2 examples of abiotic factors
Water, sunlight
How much energy is passed on from one trophic level to another?
10%
Scavengers
Feed on dead animals
Secondary consumers
Feed on primary consumers
Tertiary consumers
Feed on secondary consumers
Carnivore
Feeds directly on animals
Herbivore
Feeds directly on plants
Primary consumer
Feeds directly on plants
Omnivore
Feeds on plants and animals
Energy from the sun is used to convert carbon dioxide into what?
Glucose (a type of sugar)
The bottom of the biomass pyramid corresponds to the ____ amount of living material
Greatest
Nitrogen fixation
Required to change nitrogen in the atmosphere into nitrates and ammonia (a form that plants can use)
Biotic factors (give 3 examples)
Living Plants, animals, fungi
Habitat
Living thing in an ecosystem that has a place which it lives in
Food web
Many food chains that are connected together
Oxygen cycle
Moves oxygen through an ecosystem
All organisms need energy to do what?
Moving, feeding, producing, and growing
Nitrogen cycle
Nitrogen moves through an ecosystem
Abiotic factors (give 3 examples)
Non-living Water, sunlight, oxygen

Photosynthesis and cellular respiration
Carbon cycle
Process by which Carbon moves through an ecosystem
Bio geochemical cycles
Process by which nutrients move through organisms and the environment
Ecologist
Scientists who study ecology
Ecosystem
The physical environment and the living things within an ecosystem
