17
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.

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
Herbivores
plant eaters
26
Heterotrophs
or consumers: organisms which depend on other organisms for their food
27
Intrinsic rate of increase
the population growth rate
28
Logistic growth pattern
a realistic growth pattern when a population is stable
29
Mutualism
A relationship between two species in which both species benefit
30
Nitrogen cycle
how nitrogen compounds are transferred from bacteria, converted to ammonia, transferred to soil, and then to humans and animals
31
Omnivores
creatures which are both plant and meat eaters
32
Parasitism
A relationship between two organisms of different species where one benefits and the other is harmed
33
Phylum coniferophyta
conifers
34
Populations
Groups of organisms of the same species, which exist within ecosystems
35
Producers
Autotrophs, which make their food from inorganic energy sources.
36
Symbiosis
organisms in close relationships
37
Each step in a food chain or food web; each layer of an ecological pyramid represents a different type of organism and how they feed
Trophic level
38
biomes which are hot, humid areas that receive an abundance of rain and support a diverse range of living things
Tropical rainforests
39
Tundra
biomes which are characterized by long winters with cold temperatures, short summers, and frozen land called permafrost
40
Water cycle
how water moves from the bodies of water on the earth, through the atmosphere, and back to the earth again.
