What type of energy is sunlight?
|
radiant energy
|
|
|
Define Chemical energy
|
energy that is stored in the bonds of food molecules
|
|
|
describe autotrophs
|
gain energy via photosynthesis or chemosynthesis
|
|
|
How do Autotrophs store energy?
|
the energy is converted into chemical energy and stored in the carbon-carbon bonds of organic molecules
|
|
|
describe Heterotrophs
|
obtain energy by consuming energy rich organic compounds from other organisms
|
|
|
Describe parasites
|
lives off a host. may or may not cause death
|
|
|
describe herbivores
|
eat plants. may or may not cause death
|
|
|
describe predators
|
eat living prey. prey dies and there is a reduction in the prey population size
|
|
|
describe detritivores
|
live off nonliving organic matter (decomposers)
|
|
|
What does sunlight provide to autotrophs and how is it used?
|
Sunlight provides the energy to take up CO2 and synthesize organic compounds. Most biologically available energy comes from photosynthesis

|
What type of plants use C3 photosynthetic pathway?
|
plants that lack a specialized biochemistry
|
|
|
What occurs in C3 plants?
|
photorespiration co-occurs and results in a net loss of energy
|
|
|
What does C4 photosynthetic pathway do?
|
reduces photorespiration
|
|
|
give examples of C4 species
|
many grass species (corn, sugarcane, and sorghum)
|
|
|
What have heterotrophs evolved in order to acquire energy more efficiently?
|
specialized tissues and organs for absorption, digestion, transport and excretion
