Ecosystem Structure
|
A. A bird’s nest can tell a story about the life of the bird that builds the nest.
It can tell a scientist • what twigs the bird prefers to make its nest out of • how many eggs the bird lays • what time of year the bird mates • how much competition the bird has (by how spread apart the nests are in the area) • how much dedication the parents give their offspring |
|
|
Niche
|
All the activities an organism does throughout its life. Including
• What it eats (its prey) • What eats it (its predator) • What time it is active (diurnal or nocturnal) • What its mating preferences are (bird with bright colors perhaps or a pretty song) • Whether or not it migrates • Habitat (where an organism lives) |
|
|
Habitat
|
Where an organism lives Including
• A certain biome the organism lives in (temperate deciduous forest, tropical rain forest, desert) • Where in the tree it may live • Which specific nest it lives in |
|
|
Abiotic Environment
|
Nonliving environment
|
|
|
Biotic Environment
|
Living environment
|
|
|
Population
|
A group of the same species living in a specific area
|
|
|
Community
|
A group of different populations interacting together
|
|
|
Ecosystem
|
Both the abiotic and biotic environments interacting together
|
|
|
Biosphere
|
The part of the earth that organisms can live in (from the tops of mountains to the
depths of the oceans). |
|
|
Autotroph
|
An organism that makes its own
food (plant) |
|
|
Heterotroph (consumer)
|
An organism that
needs to eat to get food (animal) |
|
|
Decomposer
|
An organism that breaks down
dead organic matter and returns the nutrients to the ecosystem (worms, bacteria) |
|
|
Scavenger
|
An organism that feed on already
killed organisms (vultures, hyenas) |
|
|
Parasite
|
An organism that feeds off of living organisms. Parasites often don’t want to kill their hosts but they do harm their hosts by taking some of their nutrients (ticks, tapeworms).
|
|
|
Food Chains
|
Only show one part of an entire
food web. Remember, the arrow always points to the organism that is eating, this is because the arrows represent the flow of energy. |
|
|
Food webs
|
Show detailed predator/prey relationships within an ecosystem
|
|
|
Trophic pyramid
|
A graphic representation that shows the amount of energy available to each trophic
level. Only 10% of the energy at each trophic level is passed on to the next level. That means that 90% of the energy is lost between each level, this is due to the organisms spending so much of their energy on metabolism, only 10% is stored. |
