Biomes
Which two biomes are the most similar with regard to rainfall?
tundra and desert
All the nonliving parts of an ecosystem are referred to as:
Abiotic Factors
Producers
Organisms which make their own food and are the source of all food in an ecosystem
Process by which water move from a liquid state to a gaseous state
Evaporation
the area where a population lives
Geographic Range
Which biome is characterized by a layer of permafrost?
tundra
A group of ecosystems that have the same climate and similar dominant communities.
Biome
An organism that must feed on other organisms to get energy
Consumers
Water moves from the atmosphere to the geosphere
Hydrologic/Water Cycle
Population Growth =
(Births + Immigrants) - (Deaths + Emigrants)
Biodiversity is greatest in which biome?
rain forest
All the living things that live and interact together with the nonliving environment within a particular place.
Ecosystems
Organisms that break down wastes and dead organisms and return the raw materials to the environment
Decomposers
Carbon enters the atmosphere from:
Decomposition, burning fossil fuels, animal respiration, animal waste
Density- Dependent Factors
Competition
Disease
Overcrowding
The eastern portion of the United States is dominated by what biome?
Temperate Forest
Carrying Capacity:
the maximum population size that a certain environment can support at a given time.
Explain the difference between Weather and Climate
Weather: day-to-day conditions at a particular place and time
Climate: average, year-after-year conditions in a region
Most important part of nitrogen cycle
Bacteria for fixing nitrogen
Demography
study of human populations
All the different species of an ecosystem are referred to as the:
community
Competition
The struggle between organisms to survive in a habitat with limited resources
What are the different types of Heterotrophs
- carnivores - Meat
- herbivores - Plants
- omnivores - Plants and Meat
- detritivores - decomposing material
Define these terms
- condensation
- precipitation
- transpiration
- sublimation
- deposition
Condensation: the conversion of a vapor or gas to a liquid.
Precipitation: water released from clouds in the form of rain, freezing rain, sleet, snow, or hail
Transpiration is the process of water movement through a plant and its evaporation from aerial parts
sublimation: conversion of a substance from the solid to the gaseous state without its becoming liquid
Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice.
Carrying Capacity
the number an environment can support
