Define Ecology
The study of the relationships between organisms and their habitat.
How does photosynthesis contribute to ecology?
Solar radiation is made available through the process and energy is stored in primary producers.
What type of animals only eat plants?
Herbivores
Why do we study ecology?
Provides new knowledge between people and nature.
Ultimately who are the caregivers for the environments around us?
Us. The communities, interest holders and indigenous people in an ecosystem.
Define Autotroph
An organism that can produce its own food
How much energy is passed from one trophic level to another?
10%
What type of animal is both carnivorous and herbivorous?
Omnivores
What are some of the categories of ecology that we have studied in Unit 1?
Organisms, communities, population and ecosystem.
Which scientist is best known as the father and architect of the theory of natural selection?

The living components in an environment
Are Earth's matter and resources finite?
True
What are the 6 levels of ecology?
Biosphere, biome, ecosystems, community, population, species
What ecosystem have we been studying to learn ecology?
Serengeti.
Who is the researcher who stumbled upon the poachers campsite and studied the wildebeest migration patterns?
Dr. Mduma
Define Abiotic
The non-living components in an environment.
Predators, drought, (food) grass to herbivores & prey to carnivores that contribute to a limit in population growth is an example of?
Limiting factors
Wildebeest in the Serengeti are considered this. Where other species are dependent on them.
Keystone species.
The total sum of an environments resources and ability to sustain a population of a group is called?
Carrying capacity
Who were responsible for the near extinction of the American Bison in the American West.
Settlers in the American West.
Define a Biome
Cover large areas and are characterized by their climate and the types of plants and animals that are found there
What is the ultimate source of energy for our planet?
Sun
Animals that normally control population from the top down in a trophic pyramid.
Predators
What is the difference between limiting factors and carry capacity. How are they related?
Limiting factors contribute to caps in population growth. Carry capacity is the combined limiting factors and resources that contribute to how much a population can be sustained in an ecosystem.
