Q

biomes characterized by four different seasons, and home to broad-leaved deciduous trees

A

Deciduous forests

18
Q

Decomposers

A

organisms which consume dead matter by secreting enzymes that break it into simpler matter which becomes part of our soil.

19
Q

Deserts

A

hot, dry biomes that receive very little rain

20
Q

Detritivores

A

organisms which feed on dead matter by breaking it into smaller components, speeding up the decay process.

21
Q

Ecosystems

A

A biological community of interacting organisms and their physical environment; a subdivision of a biome.

22
Q

Exponential growth pattern

A

an increasing growth pattern that could occur if a population had limitless resources.

23
Q

An energy chain which presents a more complex understanding of how energy flows through an ecosystem, allowing us to see how food chains are connected and interwoven.

A

Food web

24
Q

biomes which are temperate regions that experience different seasons, but not enough rain to support trees; however, are able to support grasses

A

Grasslands

25
Q

Herbivores

A

plant eaters

26
Q

Heterotrophs

A

or consumers: organisms which depend on other organisms for their food

27
Q

Intrinsic rate of increase

A

the population growth rate

28
Q

Logistic growth pattern

A

a realistic growth pattern when a population is stable

29
Q

Mutualism

A

A relationship between two species in which both species benefit

30
Q

Nitrogen cycle

A

how nitrogen compounds are transferred from bacteria, converted to ammonia, transferred to soil, and then to humans and animals

31
Q

conifers

34
Q

A

Trophic level

38
Q

biomes which are hot, humid areas that receive an abundance of rain and support a diverse range of living things

A

Tropical rainforests

39
Q

Tundra

A

biomes which are characterized by long winters with cold temperatures, short summers, and frozen land called permafrost

40
Q

Water cycle

A

how water moves from the bodies of water on the earth, through the atmosphere, and back to the earth again.
