Producer |
use photosynthesis to turn sunlight into food Example: Grass takes sunlight and turns it into food |
|
Herbivores |
eat producers because the can't make their own food Example: cows eat grass only |
|
Carnivores |
eat meat/herbivores and omnivores Example: Foxes eat cows and other meat only |
|
Omnivore |
eat both plants and meat Example: Humans eat meat and fruits |
|
Consumer |
Can't make their own food so eat other things Example: all animals that are alive |
|
Detritivore |
eat dead plants or animals and break down materials to be used in other things Example: Worms and insects eat rotten apples |
|
Food Chain |
models how energy flows in an ecosystem through feeding relationships Example:grasshoper eats a plant the mouse eats the grasshopper & the snake eats the mouse |
|
Food Web |
a model that shows several connected food chains Example: a rabbit eats a plant and a coyote eats the rabbit the coyote also eats the chipmunks |
|
Energy Pyramid |
show the amount of energy available at each step of a food chain Example: Producers 100% Primary 10% Secondary 1% Third 0.1% Fourth 0.01% |
|
Oxygen Cycle |
Example: 6Co2 + 6H2O + energy -> C6 H12 O6 + 6 O2 |
|
Carbon Cycle |
CO2 + H2O + light => C6H12O6 + energy or fuel + oxygen -> heat + water + Carbon Dioxide |
|
Photosynthesis |
the way plants get their food -6Co2 + 6H2O reactants -> 6O2 + C6H2O2 Products |
|
Population |
made up of all the members of one species that live in an area |
|
Community |
all populations living in an ecosystem at the same time |
|
limiting factors |
are factors that can limit the growth of a population Example: predators, disease |
|
Biotic Potential |
the potential growth of a population if it could grow in perfect conditions with no limiting factors |
|
Carrying Capacity |
The largest number of individuals of one species that an ecosystem can support over time |
|
Habitat |
the physical place where a population or organism lives |
|
Niche |
the unique way an organism survives ,obtains food and shelter, and avoid danger in its habiat |
|
Symbolic Relationship |
one in which two different species live together and interact closely over a long period of time |
|
Population Size |
can increase or decrease |
|
Population Density |
describes the number of organisms in a population relative to the amount of space available |
|
Overpopulation |
A population becomes larger than an ecosystem's carrying capacity |
|
Mutualism |
a Symbolic Relationship in which two species in a community benefit from the relationship Example: |
|
Parasitism |
a symbolic relationship in which one species (the parasite) benefits while another (the host) is harmed Example a tick in a dog |
|
Commensalism |
a symbolic relationship where one species benefits and the other is neither helped or harmed Example:barnacles on whales stomachs |
|
Prey |
an animal hunted or seized for food especially by carnivores |
|
Predator |
any organism that exist by preying upon other orginisms |
