Ecology in Biology

In a Central Texas grassland, the producers incorporate 12,000 kJ of energy from the sun into their tissues. About how much energy would be incorporated into the tissues of herbivores?

• 12,000 kJ

• 1,200 kJ

• 10,800 kJ

• 1,080 kJ

After a wheat field is cleared, wild grasses and weeds begin growing. This process is considered —

• primary succession because pioneer species appear 

• primary succession because there are no large trees

• secondary succession because soil is already present

• secondary succession because the field contains inorganic matter

How is an ecosystem different from a community?

• They are the same

• An ecosystem includes the interaction between a community of organisms (biotic factors) interacting with their environment  (abiotic factors) 

• An ecosystem has only abiotic factors

• An ecosystem is more specific

What is a biotic factor?

• Geographic Features 

• Living things

• Hydrologic Cycle

• Non-living things

Since species within an ecosystem depend on one another, why don't populations of species continuously grow? 

• Not enough food, water, shelter

• Organisms don't reproduce

What is a population?

• organism 

• Groups of individuals of the same species living in a particular area

• All life, biotic and abiotic in an area

• Groups of non-related/multiple species living in the same area

What is a community?

• species living in a given location

• Biotic and Abiotic Factors

• Many populations living in the same location
