This level of organization contains organisms that can produce fertile offspring and live in a defined area

Population

These the levels of nutrition in a food chain.

Trophic levels

This is the level of organization containing groups of several species in an area.

Community

When a non-water soluble pollutant enters the ecosystem, it is in greatest concentration on this level.

Top consumer level

These organisms are likely at the top of the food chain, yet do not hunt and kill.

Scavengers

These organisms can make their own food from sun energy or chemicals.

Autotrophs

These organisms feed upon plants and animals

Omnivores

An ecosystem contains 34,640 Calories at the bottom trophic level. How many Calories are available to the third trophic level?

346.4 Calories

These organisms are at the first trohpic level

Producers/ Autotrophs

Theoretically, a food chain could have infinite trophic levels Theoretically, a food chain could have infinite trophic levels. Realistically, why can’t it?

If only 10% is passed up to the next level, so little energy would get to those high trophic levels that they would be required to eat too much biomass to be satisfied (they would never stop eating).

Water enters the atmosphere through these two processes

Evaporation and transpiration

Organisms need nutrients in order to do this

Carry out life processes

Nitrogen is made into a form that plants can take in my this process

Nitrogen fixation

What are the 4 ways that carbon enters the atmosphere?

Volcanic eruption exhalation of organisms burning of fossil fuels CO2 in ocean being released

This nutrients is essential for nucleic acids (DNA) and it never enters the atmoshpere.

Phosphorus

Define weather and climate.

Weather is day to day conditions Climate is an average of temperature and precipitations for an area

The tropical rain forest, tropical dry forest, and tropical savanah all lie within these latitudes.

23.5 N and 23.5 S

Water heats and cools (slower or faster) than land.

slower

These gases (list them) are responsible for keeping our climate livable on Earth.

CO2, water vapor, methane

These two biomes receive the least amount of precipitation annually

Tundra and desert

This term refers to two organisms of the same kind competing for resources or mates

Intraspecific competition

This term refers to two organisms of a different species living closely

Symbiosis

List three ways humans threaten biodiversity.

Demand for wildlife products Habitat destruction Pollution Introducing Non-native species

After a fire, the steps to rebuilding a community here is described as this.

Secondary succession

There are tiny unicellular organisms called zooflagellates living in the intestines of termites allowing them to digest cellulose from wood. What kind of relationship is described here?

mutualism
