What is an ecological pyramid?
|
Diagrams that can show the transfer of energy, # of organisms of biomass through each trophic level.
|
|
Where does the rest of the energy from the trophic level go?
|
1.Not all body parts are available
2.It takes energy to make energy 3.Consumers only get the energy in the body at the moment 4.something on each trophic level must survive to reproduce |
|
Ecology
|
the study of relationships between organisms and their environment
|
|
niche
|
defines an organism's lifestyle. Takes into account it's habitat, nutrition, foraging and territory

Symbiosis
|
When organisms of two different species share an unusual relationship.

|
Pioneer Species
|
The first species to inhabit an area after a disturbance.
|
|
climax community
|
This consists of plants that will remain in the area. It is stable and fairly diverse.
|
|
Tundra
|
A biome that is up north with few trees. There is a short growing season with grasses and wildflowers.
|
|
Taiga
|
A northern forest of twisted and small conifers. There is a lot of wind and harsh winters.

Temperate Deciduous Forest
|
Biomes that are mostly in the Northeast and Middle Atlantic United States. The trees all drop their leaves in the winter. There are average amounts of precipitation with warm summers and cold winters

Grasslands
|
These biomes are often found in the Midwest United States. Many grasses grow here. Summers are warm and winters are cold. Rainfall is unpredictable.
|
|
Deserts
|
This biomes is dry with hardly any precipitation. Large temperature shifts occur. There are abundant cacti.
|
|
Tropical Rain Forests
|
This biome is filled with diverse animal life. There is a lot of rain and humidity. There is a lot of plant life, but poor soil quality.
|
|
Estuary
|
This biome occurs anywhere where the ocean meets fresh water. This creates brackish water with specific grasses and crustaceans.
