Ecology Part 1-4

Energy flows through an ecosystem in one direction from the sun or chemical compounds to autotrophs (producers) and then to various heterotrophs (consumers).

Multiple Choice

An organism that needs to eat other organisms to obtain energy is known as a:

Autotroph

Producer

Consumer

Mutualist

Multiple Choice

The largest group of organisms found in a food web would be:

Primary Consumers

Producers

Decomposers

Tertiary Consumers

Multiple Choice

In the energy pyramid below, which organism has the least amount of energy available?

Producers

Herbivores

Carnivores

Top Predator

Multiple Choice

In the energy pyramid here, which organisms have the most energy available?

Producers

Carnivores

Herbivores

Top Predator

Niche

An organisms role in their environment
For example: like a job, like a worker in a factory has a job to do

Multiple Choice

What is a habitat?

Where an organism lives.

What an organism eats.

A organisms role, or job, in its ecosystem.

Multiple Choice

What is a niche?

Where an organism lives.

An organisms role, or job, within its ecosystem.

What an organism eats.

Multiple Choice

A whale's niche would be which of the following?

eating plankton and krill.

eating sharks and dolphins.

eating hamburgers and fries.

eating other whales.

Multiple Choice

A squirrels niche would be _________________.

hunting prey and providing meat for other squirrels.

searching for fish to eat in the ocean.

staying busy storing nuts and seeds for winter.

help decompose other animals and plants.

Multiple Choice

A niche ________________.

is the function that an organism performs in the food web of that community.

includes everything else the organism does and needs in its environment.

is specific to each individual animal and plant.

All of the above.

Biogeochemical cycles

Elements, compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another; Connect biological, geological and chemical aspects

Water, Carbon, Nitrogen

Water: Water is constantly moving between

the atmosphere & Earth.

Carbon: Carbon plays many roles – 4 main processes move carbon:

•Biological processes, such as photosynthesis, respiration and decomposition

•Burial and decomposition of dead organisms and their conversion under pressure (fossil fuel)

•Geochemical processes, such as erosion and volcanic activity release CO2

•Mining, cutting and burning forests, burning fossil fuels

Nitrogen: The atmosphere is the main reservoir of nitrogen; it also cycles through the soil and tissues of living organisms.

Multiple Choice

All living things contain carbon.

True

False

Multiple Choice

Carbon can be found in

the ocean and seas

rock and mantle of the Earth

the atmosphere

all of these are correct

Multiple Choice

Death and decomposition are part of many life cycles. What else helps return nitrogen and carbon to the ground?

animal waste

lightning

rain

DNA

Multiple Choice

Which of the following is represented by this picture?

the water cycle

the carbon cycle

the nitrogen cycle

the hydrogen cycle

Multiple Choice

Which of the following is represented in this picture?

the water cycle

the carbon cycle

the nitrogen cycle

the hydrogen cycle

Multiple Choice

Which of the following is represented in this picture?

the water cycle

the carbon cycle

the nitrogen cycle

the hydrogen cycle

Symbiosis

Any relationship in which two species live closely together

Mutualism

both species benefit from relationship

Commensalism

Onse species bennefits while the other species is unaffected

Parasitism

Parasitic species bennefits while the host species is harmed.

Multiple Choice

A sparrow will build its nest under the nest of an osprey. The smaller birds get protection because other predators will not mess with the osprey. The osprey are not helped nor harmed by the sparrow.

parasitism

commensalism

mutualism

Multiple Choice

Remoras attach themselves to a shark’s body. They then travel with the shark and feed on the leftover food scraps from the shark’s meals. The relationship neither harms nor benefits the shark.

parasitism

commensalism

mutualism

Multiple Choice

Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds. Both species benefit.

parasitism

commensalism

mutualism

Multiple Choice

Aphids are tiny insects that live on and eat the leaves of plants, removing vital nutrients from the plants.

Predation

Parasitism

Commensalism

Mutualism

Multiple Choice

A relationship between two organisms in which both organisms benefit.

Mutualism

Competition

Parasitsm

Commensalism

Multiple Choice

Which symbols best describe parasitism?

+,+

+,-

+,0

-,0

Multiple Choice

What type of symbiosis? Hummingbirds feed on nectar from flowers. The flowers are pollinated by hummingbirds as they move from flower to flower.

commensalism

mutualism

parasitism

predation

Multiple Choice

mutualism

commensalism

competition

parasitism
