Chapter 3,4,5,6 test

Harmful material that can enter the biosphere through land, air, or water

How much percent of air does atmospheric Nitrogen make up

Increasing by and ever increasing rate - population explosion

Band of ozone, a gas made up of 3 oxygen atoms, that surrounds our planet/ depletion occurs through CFC’s

When organsisms attempt to use the same resources at the same time

Possible pathways of biological, geological, and chemical aspects of the biosphere

Plants DONT release oxygen through transporation

Consumers that feed on plants only: Ex- cows, rabbits, grasshoppers, rodents

The sum total of the variety of organisms in the biosphere

Animals that feed on carrion(dead meat)

Where are phosphates cycled between soils and terrestrial(on land) organisms

Feed on small particles of plant and animal remains known as detritus( snails, earthworms, crabs)

Eat both plants and animals

Mainly weather and natural disasters which can limit population growth, population size has no affect

A relationship in which 2 species live closely together and sometimes they can’t live without each other

A series of steps in which organisms transfer matter and energy

There are 3 types of symbiotic relationships

Illustrates total amount of living organic matter with each level

After death an organism release _______ into the environment through decomposition

First level on trophic levels- algae, marsh grass

All living organisms that inhabit the environment

Fourth level on trophic levels- omnivore or carnivore, alligator, humans OFTEN MEDIUM SIZE

The prey points to what eats it

When populations growth slows or stops following and exponential growth

Group of organisms so similar to one another that they can breed and produce fertile offspring

Overcrowding causes stres which can result in aggression, decrease in parental care, decrease fertility, and less diseas

The natural situation in which heat is retained by the gases surrounding earth

Sunlight is the main source of energy on earth

Bio- life Geo- Earth( rocks,water,sand)

What does the water cycle begin with?

Areas which are greatly affected by the tilt of the earth during the year, temperatures range from hot to cold

Destruction of forest

One organism captures and feeds on another organsism

Animals release Oxygen by breathing and excrete( let out) H2O from pee and sweat

Rate at which organic matter is created by producers in an ecosystem

A collection of interacting populations no population of organisms lives independently of other species

Unequal heating of earths surface creates winds and ocean currents and affect climate

Nutrients which are scarce or cycles very slowly, limiting the productivity of the ecosystem

Scientific study of interactions between organisms and their environments

The nonliving parts of the environment( air currents, temperature, moisture, light and soil

Farming strategy where large fields are planted with a single crop year after year

Weaken and takes the nutrients away causing death

Liquid, solid, and a gas

The role a species play in a community

Can regenerate quickly and therefore replacable/ water, grass, trees, air, ocean resources, land, fish, oxygen

When rocks are weathered phosphate is released

Refers to the average conditions of the atmosphere over time

The change in the size of population with time

Third level on trophic levels-omnivore, or carnivore, birds, coyote , fox , bear OFTEN SMALL

Organisms that use energy from the sun or stored energy in chemical cpds to make their food

A relationship in which both species benefit

Cold areas where the suns rays strike earth at a very low angle

Group of ecosystems with the same climates

Second level on trophic levels- herbivores, mussels, and grasshoppers

Organisms that depend on autotrophs as their source of nutrients and energy

Competition for food, water, and territory become more common with higher population and presentation make less people

Many organisms get carbon by consuming producers

Animals drink H2O or get it through food

Carnivores eat 98% meat

Autotrophs are producers? Plants are common autotroph they harness solar energy through photosynthesis

Every organism in a community has a unique niche… one organism may have many niches in a community

H2O will move over to land as runoff or soak into the ground( seepage) after water cycle

A little extra warming WONT cause problems for humans, plants and animals

Shows relative number of individuals at each level

Portions of earth that supports life it extends from high in atmosphere to bottom of ocean

A relationship which one organsism benefits at the of the other, host usually not killed

Mainly found in soil and rock minerals and in ocean sediment

Resources that cannot be replenished by natural processes: fossil fuels, oil, natural gas

Areas near the equator which receive direct sunlight year round

Making food with chemical energy instead of light Ex. Chemisynthetic bacteria

Fifth level in trophic levels, omnivore or carnivore, humans, sharks OFTEN LARGE

Surface H2O evaporates and rises into air where it condensed(liquid to gas) the precipitates back to ground

The gases that form the “blanket” around earth are primarily carbon dioxide, methane, and water vapor

Immigration is the movement INTO a population and Emigration is movement OUT of a population

Groups of individuals that belong to the same species and live in same area

The day to day conditions of Earths atmosphere at a particular place and time

Only to acquire basic necessities for survival makes few demands on environment

Interactions among populations in a community and the physical surrounding

Factors that cause population growth to decrease(food, space

Practice of farming

Animals that kill and eat only other animals

The ozone layer is a build up of carbon dioxide and methane gas in the atmosphere

The burning of fossil fuels also return CO2 to the atmosphere which is a great _______

Organisms that break down and absorb nutrients from dead organisms( fungus, and bacteria)microscopic

What do organisms return to the atmosphere when they die and decay (dentrification)

One species benefits and the other is neither harmed or benefited

What converts nitrogen into protein

Density dependent factors happen more with higher population

Number of individuals per unit area

Without this our earth would not be warm enough for humans to live

Heterotrophs are also known as consumers
