Slides 1-5
What is Define Ecology is
The scientific study of interactions among organisms and between organisms and the environment.
What is a Species?
Species is a Species - group of organisms so similar to another that they can breed and produce fertile offspring
What is a Define Niche?
A niche is the role the species plays; it includes types of food it eats, where it lives and reproduces, and other relationships wit others.
How does energy flow from producers to consumers?
Energy flows through an ecosystem in one direction from the sun to the consumers.
What is the primary succession?
succession that occurs on the surface where no soil exists
What does Biosphere contain?
Biosphere contains the combined portions of the planet in which all of life exist, including land, water and atmosphere
what is the Population?
The Population is a Population of the same species and lives in the same area
What cycles affect the ecosystems?
These are some of the cycles:
Polar ice
tropical monsoon forest
rain forest
desert
what is the food chains?
A food chain is a series of steps in which organisms transfer energy by eating and being eaten.
what is the Examples of Pioneer Species
Lichen
What is the names of the worlds ecosystem parts?
Biosphere, Atmosphere, Ecosphere, Hydrosphere, and Lithosphere
What is the Community?
The Community is a Communities of different populations that live together in a defined area
What are the stages of the water cycle?
Condensation, transpiration, precipition, surface runoff, evaporation and accumulation.
What is the food web?
A network of complex feeding relationships among the various organisms in an ecosystem
What is the Secondary Succession
Secondary Succession – following a disturbance that destroys a community without destroying the soil.
What is the Level of Organization of an Ecosystem
The Level of Organization of an Ecosystem is
What is the Ecosystem is
The Ecosystem is a Ecosystem of a collection of all organisms that live in a particular place together with their nonliving environment.
What are the Definitions of Water Cycle?
Evaporation – process of becoming a vapor; liquid to a gas
Condensation – state of matter from gas to liquid; reverse of vaporization
Precipitation – the amount of water that falls to earth as snow, sleet, hail, rain, mist
Transpiration – loss of water from a plant through its leaves
Runoff – the flow of water, from snow and rain
Infiltration – process by which water on the ground enters soil
What is the Energy Pyramid
Trophic level is each step in a food chain/web
A diagram that shows the amount of energy or matter contained within each trophic level in a food chain/web
Only about 10% of the energy available within one trophic level is passed to organisms in the next trophic level.
What is the Example of Secondary Succession
Example- land cleared and plowed for farming
Example – Fires set by lightning
What is the Level of Organization of an Ecosystem?
The Level of Organization of an Ecosystem is Biosphere, Biome, Ecosystem, Community, Population and Individual.
What is the Biome is?
The Biome is a Biome of a group of ecosystems that have the same climate and similar dominant communities.
Define the Carbon Cycle?
Animals eat plants, combustion gives off carbon, green plants absorb, Decomposing matter gives off carbon.
What is the Ecological Succession?
Ecological Succession a series of predictable changes in an environment
How long it take for the forest to get back to it's original state
150+ years
