If a population grows larger than carrying capacity the______

• population will grow faster.

• carrying capacity will change.

• death rate will likely rise.

• birthrate will likely rise.

True or False. Any factor the causes a populations growth to decrease is a limiting factor.

• True

• False

The process organisms use to keep their internal conditions stable is called.

• photosynthesis.

• homeostasis.

• metabolism.

• cellular respiration.

Organisms that CANNOT make their own food are called_____ (which is the BEST answer?)

• plants

• heterotrophs

• autotrophs

• decomposers

Which of the following is NOT a stage of cellular respiration?

• calvin cycle

• krebs cycle

• electron transport

• glycolysis

Carbon cycles through the biosphere in all of the following processes EXCEPT

• photosynthesis

• decomposition

• respiration

• transpiration

The movement of energy and matter (nutrients) through living systems is different because_____

• energy flows in one direction (sun to organisms) and matter is recycled

• energy is limited and matter is always available

• energy forms chemical compounds to create molecules and matter is lost as heat

• matter flows in one direction (sun to organisms) and energy is recycled

If there is no carbon dioxide for a plant you would expect what?

• no glucose (sugar) to be produced

• no change

• the plant will produce co2

• more glucose (sugar) to be produced

Energy is released from ATP when

• ATP is charged by the sun

• a phosphate group is added

• the sugar is digested

• a phosphate group is removed

The grasses in the food web are

• heterotrophs

• producers

• consumers

• decomposers
