an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide
autotroph
the deeper layer of ocean water that lacks sufficient sunlight for photosynthesis
aphotic zone
portion of the marine biome that is shallow enough for sunlight to penetrate
photic zone
consumer that feeds directly on producers
primary consumer
a carnivore at the topmost level in a food chain that feeds on other carnivores; an animal that feeds only on secondary consumers
tertiary consumer
The APHOTIC ZONE differs from the photic zone in that is lacks
sunlight
Based upon the definition, which of the following is NOT an AUTOTROPH?
a maple tree
a sunflower
a photosynthetic bacterium
a human
Of the following would a PRIMARY CONSUMER consider a worthy meal: algae, beetle, rabbit, dandelion?
algae and dandelion
network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem
food web
an organism that eats primary consumers
secondary consumer
Of the following would a SECONDARY CONSUMER consider a worthy meal: algae, beetle, rabbit, dandelion?
rabbit
any biotic or abiotic factor that restricts the existence, numbers, reproduction, or distribution of organisms
limiting factor
tiny algae and animals that float in water and are carried by waves and currents
plankton
series of steps in an ecosystem in which organisms transfer energy by eating and being eaten
food chain
The APHOTIC ZONE differs from the photic zone in that is lacks
sunlight
A PRIMARY PRODUCER would be found where in a food chain/food web?
at the bottom, receiving energy directly from the Sun
near the bottom, receiving energy from an autotroph
near the middle, receiving energy from both autotrophs and h
at the top, receiving energy from a heterotroph
