part 1
Living factors in a biome are called
biotic
More than half of all plant and animal species on earth live here, near the equator
Tropical rain forest
the study of the interactions between organisms and their environment is
ecology
Explain the difference between traits that are inherited and acquired. Give examples
Inherited- genetic (on DNA) passed from parents to offspring
Ex. hair color, height
Acquired- traits that changed over time due to the environment ex. large muscel size to avoid predators
Non-living parts of an ecosystem are called
abiotic
Microscopic algae, tiny animals and plants that float near the surface of the water are called
plankton
Organisms that feed on dead organisms are
decomposers
What is the difference between a food chain and a food web? You may draw a picture.
Chain- straight line/linear of a feeding event; always starts with producer
Web- multiple chains that are interwoven
Region where plants or animals grow and live (native environment) is
habitat
Arrangement of organisms of an ecological community according to the order of predators in which each uses a lower member as food source is a(n)
food chain
herbivores, carnivores, and scavengers are considered
consumers
permanently frozen ground is called
permafrost
the role of an organism in a nature is a
niche
an organism that makes its own food is a(n)
Producer/autotroph
The average rainfall and temperature in an area is called
climate
The first trophic level in a food web is made up of
Producers autotroph
The ultimate source of energy is the
sun
