Give at least 2 examples of a BIOTIC limiting factor.
Disease (bacteria), food availability, predators, etc.
200
What is metabolic rate?
The rate an organism burns food for energy. This would be increased by activity.
200
What is the difference between biotic and abiotic factors?
Biotic factors are living organisms and Abiotic factors are non-living factors in an ecosystem.
200
What is geotropism?
Something biotic responding to gravity.
300
Identify a possible limiting factor that can cause the mouse population to reach its carrying capacity. 
Limiting Factors: predators, habitat, competition for resources
300
Give at least 2 examples of ABIOTIC limiting factors
drought, severe winter, natural disaster, virus-caused diseases, etc.
300
Why do canopy trees grow so tall and not wide?
Competing for sunlight.

How is eutrophication harmful to an ecosystem?
Cause death to plants and fish in the water. Death of a Lake.

b. amount of grass/flowers available
c. the amount of sunlight
d. rabbits have no limiting factors
b. amount of grass/flowers available

What's the difference between native species and invasive species?
Native have always been in the ecosystem.
Invasive species were brought from another ecosystem.

Prophase - Metaphase-Anaphase-Telophase-Cytokinesis

Define Eutrophication.
Nutrients get into water--Algae grow at fast rate--Pond covered in algae--plants die due to lack of sunlight--Fish die due to less oxygen because plants died and algae consuming oxygen
500
In an ecosystem, what can cause the decrease of a population?
Predation, lack of food supply/habitat, deforestation

Define Ecosystem
All the biotic and abiotic things in an area.
