100

The study of the interactions that organisms have with their environment

Ecology

100

A single individual

Organism

100

Any close relationship between two or more species that live together

Symbiosis

100

This is an organism that has to eat food to get energy

Heterotroph

100

Something that prevents a population from increasing

Limiting factors

100

What molecule is considered the backbone of all living things?

carbon

200

The portion of the Earth that supports life

Biosphere


200

Which of the following levels of organization includes all of the other levels?

Community              Individual

Ecosystem              Population


Ecosystem

200

What type of symbiotic relationship is represented here:

Parasitism

200

The picture to the shows an example of a ___?

Food web

200

What is the carrying capacity of rabbits in this ecosystem?

Around 300 because the line fluctuates around that number

200

This process converts the energy of the sun into a form that can used be living things

photosynthesis

300

What is the difference between a biotic factor and an abiotic factor?

Biotic – Living (or once living) factors

Abiotic – Non-living (never alive) factors

300

What level of organization do these giraffes represent?

Population

300

List the 3 major types of symbiosis

Commensalism, Parasitism, Mutualism

300

Is this an autotroph or heterotroph. Explain how you know?

An autotroph because it uses the sun’s energy for photosynthesis

300

Is the limiting factor in the picture considered density-dependent or density independent? Explain why.

Density independent because it affects the population regardless of size

300

What organism converts nitrogen to a useable form for plants to use?

bacteria

400

List 4 biotic factors in this ecosystem

fish, ducks, frogs, dragonfly, snail, grass, plant, etc.

400

List the levels of organization from largest to smallest.

Biosphere, Biome, Ecosystem, Community, Population, (Species), Organism

400

A remora is a fish that gets a free ride from a shark and eats the bits of food that the shark leaves behind. This is an example of _____.

Commensalism

400

Define the following consumers:

Carnivore

Herbivore

Omnivore

Carnivores eat only meat, herbivores eat only producers, omnivores eat both meat and producers

400

This graph shows the population of a predator and its prey.  Which line represents the predator and how do you know?

Predator is green; its population follows the availability of its food, higher trophic level so lower numbers in ecosystem

400

A natural or artificial reservoir that stores more carbon than it releases

Carbon sink

500

What are two abiotic factors that a squirrel depends on?

Air, water, temperature, climate, humidity, etc.

500

What level or organization is represented here and EXPLAIN how you know.

Ecosystem because it contains both biotic and abiotic factors in the environment.

500

What type of relationship is shown in this picture and EXPLAIN WHY.

Mutualism because the bee is getting nectar from the flower and the flower is getting help with pollination from the bee

500

What are these organisms called on the trophic pyramid?

Secondary consumers

500

The pea weevil is a type of insect. The table shows the average time it takes for pea weevil eggs to hatch at different temperatures.  In what temp range would the population growth of the pea weevil be the highest?

Population growth would  be highest between 25-27 degrees

500

Label 1-4 in the picture of the carbon cycle below:

1. photosynthesis, 2. cell respiration, 3. decomposition, 4. combustion
