3846560437AutotrophsOrganisms that can produce their own organic compounds from inorganic chemicals0
3846560438HeterotrophsOrganisms that obtain food energy by consuming other organisms or products created by other organisms1
3846560439ProducersOrganisms that are capable of converting radiant energy, or chemical energy, into carbohydrates.2
3846560440Examples of producers include...Plants and algae3
3846560441Plants and algae carry out...Photosynthesis4
3846560442What is the unbalanced chemical reaction of photosynthesis?H2O+CO2+Solar Energy -> CH2O+O25
3846560443AnaerobicWithout oxygen6
3846560444Some producers make food through anaerobic environments. Instead of photosynthesis, they use the process of...Chemosynthesis7
3846560445ChemotrophsFew specialized bacteria fit this niche. They use chemosynthesis.8
3846560446Where are many chemotrophs found?Hydrothermal vents deep in the ocean9
3846560447What is the unbalanced chemical equation of chemosynthesis?O2+H2S+O2+Energy -> CH2O+S+H2O10
3846560448Net Primary Productivity (NPP)The amount of energy that plants pass on to the community of herbivores in an ecosystem11
3846560449How is NPP calculated?By using the Gross Primary Productivity and subtracting from it the amount of energy the plants need for growth, maintenance, repair, and reproduction.12
3846560450Gross Primary ProductivityThe amount of sugar that the plants produce in photosynthesis13
3846560451ConsumersOrganisms that must obtain food energy from secondary sources.14
3846560452Primary consumersHerbivores15
3846560453HerbivoresConsume producers16
3846560454Secondary consumersConsumes primary consumers/herbivores17
3846560455Tertiary consumersConsumes secondary consumers18
3846560456DetritivoresDerive energy from consuming nonliving organic matter such as dead animals or fallen leaves19
3846560457DecomposersBacteria or fungi that absorb nutrients from nonliving organic matter and wastes of living organisms and corpses.20
3846560458What do decomposers convert nonliving organic matter, living organisms, and corpses into?Inorganic forms21
3846560459Each feeding level in a food chain is called a....Trophic level22
3846560460As you increase in tropic levels, energy...decreases23
3846560461Only __% of the energy from one tropic level is passed to the next.1024
3846560462What trophic level has the most usable energy?Producers25
3846560463BiomagnificationThe increasing concentration of toxin molecules at successively higher trophic levels in a food chain26
3846560464What pesticide biomagnifies and was also written about by Rachel Carson?DDT27
3846560465BioaccumulationThe accumulation of a substance in the tissues of a living organism28
3846560466Food webA more realistic type of food chain29
