Adaptations

This type of organism can absorb energy directly from the environment.

• Heterotroph

• Autotroph

• Carnivore

• Chemotroph

Which of the following would be a drawback of being a carnivore?

• Food is easy to find and readily available

• Food has a low energy value

• Acquiring food must happen in a group

• Lots of energy is required to get food

Which of the following would NOT be an adaptation of desert plants?

• Broad flat leaves for maximum sun exposure

• Waxy coating

• Shape that reduces surface area

• Light coloring

How is CAM photosynthesis different from regular photosynthesis?

• The leaves are never directly in the sun

• Gas exchange is only done at night

• Chlorophyll is not used

• Only occurs in plants with small leaves

Which statement below describes the principle of allocation?

• Energy spent on adaptations does not increase survival

• Most species can survive in a variety of areas

• High fitness in on area equals low fitness in others

• Allocating energy to adaptations is not worth it

• Autosexual selection

• Chemosexual selection

• Intersexual selection

• Intrasexual selection

This type of organism must go find food through hunting, gathering, or herbivory.

• Heterotroph

• Autotroph

• Carnivore

• Chemotroph

This process is similar to the way plants get energy, but energy is acquired from a chemical reaction or heat.
