what is an example of a community?

All of the organisms living within a lake

Which of the following is an example of a community?

All of the organisms living within a lake.

Which of the following is an example of a population

All of the raccoons in a forest

a gas that is emitted by many energy consuming devices, such as cars and power plants. It is also the waste gas breathed out by most animals. Plants need this gas for the process of photosynthesis. Large emissions of CO2 gas has been linked to global warming because CO2 traps heat

Carbon Dioxide (CO2)

nonliving, physical features of the environment, including air, water, sunlight, soil, temperature, and climate

abiotic

another word for producer

autotroph

Organisms that obtain energy directly from photosynthesis are known as

autotrophs

Most people have pesticides and other environmental contaminants in their body. This is an example of

bioaccumulation

The populations of plants animals and microorganisms living and interacting in a certain area at a given time

biological community

a major biotic community characterized by the dominant forms of plant life and the prevailing climate

biome

the living organisms in an ecosystem

biotic

An organism that feeds only on heterotrophs is a(n)

carnivore

A relationship between two organisms of different species in which one benefits, while the other neither benefits nor is harmed

commensalism

the relation between two different kinds of organisms when one receives benefits from the other without damaging it

commensalism

any organism that has to consume or eat any other organism as food

consumer

Deforestation has the effect of

contributing to global warming

any organism, such as bacteria or fungus, that breaks down organic material as a source of food

decomposer

the study of how organisms interact with their environment

ecology

a system formed by the interaction of a community of organisms with their physical environment. Shows both abiotic and biotic factors

ecosystem

Starlings, sparrows and other European birds were introduced into the United States during the 1890's, when they were released in New York's Central Park by

evil Shakespeare fans

A biogeochemical cycle involves both living and nonliving components.

false

A grazing food web and a detrital food web can not interconnect.

false

Altitude and rainfall greatly influence the type of vegetation in a particular biome.

false

Cultural eutrophication is the leeching of minerals from the soil by acidic rain.

false

Energy cycles through an ecosystem, while chemicals (nutrients) flow through an ecosystem.

false

Excess phosphate in fresh water leads to an algal bloom, increased decomposers, and increased fish population.

false

Feces, urine, and even the death of an organism means substances are lost to the ecosystem.

false

Human activities have no significant effect on the nitrogen cycle.

false

In a sedimentary biogeochemical cycle, the element in question is withdrawn from the atmosphere and then returned to the soil.

false

In aquatic systems carbon dioxide is in the form of dissolved carbon dioxide.

false

Oxygen makes up about 78% of the atmosphere

false

The exchange pool for the carbon dioxide cycle is land plants

false

The niche of an organism is the place it lives within a community

false

higher up the pyramid the more energy

false

sun is everybody's main energy

false

in ecology, a community of organisms where each member is eaten in turn by another member

food chain

in ecology, a community of organisms where there are several interrelated food chains

food web

After a forest fire, the first signs of ecological recovery occur with the appearance of

grasses and small shrubs

another word for consumer

heterotroph

Food webs differ from food chains in that they

how more of the available feeding relationships in an ecosystem

Most extinctions occurring on the planet today are due to

loss of habitat

symbiotic relationship in which both species benefit from the relationship. example: hummingbird feeds off of and helps pollinate flowers

mutualism

During a particularly hot summer, the smallest change in temperature would likely be noted in

oceans

Organisms that can feed on autotrophs as well as on heterotrophs are known as

omnivores

Deforestation has the effect of

on land will increase, as will the average ocean temperatures

Most climate models predict that during this century, the average temperature

on land will increase, as will the average ocean temperatures

an individual living thing

organism

Which of the following IS NOT a greenhouse gas?

oxygen, O2

the relation between two different kinds of organisms in which one receives benefits from the other by causing damage to it

parasitism

Examples of symbiotic relationships include

parasitism commensalism mutualism

a group of organisms of the same species populating a given area

population

an organism that makes its own food such as most plants

producer

scavenger any organism that feeds off of already dead organism

scavenger

Food webs differ from food chains in that they

show more of the available feeding relationships in an ecosystem

Main source of energy for plants

sunlight

The processes of photosynthesis and respiration are tied together in

the carbon cycle and oxygen cycle

A foreign species of organism, introduced into a new ecosystem, will not become invasive unless

the population is sufficiently large to allow for natural breeding

Ultimately, all of the energy in most food chains or food webs comes from

the sun

true

Human activities have impacted many of the Earth's ecosystems in both good and adverse ways.

true
