All the living and non-living things that interact with each other in an environment.
100
What is flora?
Plant life occurring in a particular region.
100
What is niche?
The role in which an organism plays in its environment.
100
What is sustainability?
The capacity to endure.
200
The development of plants and animal life in an area without topsoil.
Explain what primary succession is?
200
Land that recovers after a natural disaster or other terrain-altering events occur.
Explain what secondary succession is.
200
more, stable
The _______ diverse an environment is, the more _____ it is.
200
Tundra: polar bears, shrubs, always snowing very cold
Deciduous Forest: squirrels, oaks, rainy and sunny
Compare and Contrast the animal/plant life (give 1 of each) and climate conditions in the Tundra and Deciduous Forest Biomes
200
They both develop into a climax communtiy where a varity of species live in and interact with each other.
How is primary succession similar to secondary succession.
300
False - The more diverse an ecosystem is the more stable it is.
True or False: the more diverse an ecosystem is the more threatened its populations are.
300
biotic- living
abiotic- nonliving
Give an example of a biotic and abiotic factor in an ecosystem.
300
The last step of succession.
Explain what climax community is?
300
Things that prevent a population from growing any larger.
What is a limiting factor?
400
Moss begins to grow.
What is the third step in primary succession?
400
1. Land is destroyed by a catastrophic event
2. Grass and weeds begin to grow
3. Small trees and shrubs begin to grow
4. Land gets healthy and big trees begin to grow
List the steps to secondary succession.
400
They have adapted to their environment.
What conclusions can you draw to explain why certain animals can survive in harsh climate condition?
400
Cold
What characteristics of the Tundra biome allow certain organisms to live there.
400
loss of natural habitat.
Explain what the MOST serious threat to biodiversity is?
500
Primary succession is the development of plant and animal like in an area without topsoil. Secondary succession is land that recovers after a natural disaster or other terrain-altering events occur.
Differentiate between primary and secondary succession.
500
There is more interaction, more balance within the food chains/food web
Explain how the variety of species within an ecosystem maintains stability?
500
1. Glacier moves exposing rock
2. Lichens grow on rock, break rock and turn to soil
3. Moss grows
4. Small plants, grass and small trees
5. Bigger trees, forest
List all the steps in primary succession.
500
1. Land is destroyed by catastrophic events.
2. Grass and weeds begin to grow.
3. Small trees, flowers, plants
4. Bigger trees and land eventually becomes healthy again
