Energy Flow
1 - $100

These are the first producers of energy-rich
compounds that are later used by other
organisms.

Primary Producers
1 - $200

This process uses chemical energy to produce
carbohydrates.

Chemosynthesis
1 - $300

This type of organism eats waste or debris.

Detritivore
1 - $400

If a primary producer acquires 18,765 J of
energy from the sun, how many joules would its
secondary consumer acquire assuming it is
found in the same ecological pyramid?

187.65 J
1 - $500

Photosynthesis and Chemosynthesis both rely on
this molecule to create carbohydrates.

Carbon dioxide
2 - $100

This refers to the number of individuals per unit
area.

Population Density
2 - $200

What are the three major patterns of population
distribution?

Clumped, Random, and Uniform
2 - $300

This is the maximum number of individuals of a
particular species that a particular environment
can support.

Carrying capacity
2 - $400

This refers to the number of males and females
of each age a population contains.

Age Structure
2 - $500

What are the four factors that affect population
size?

Birth rate, Death rate, Immigration, and
Emigration
3 - $100

This term is considered to be the global sum of
all ecosystems.

The Biosphere
3 - $200

Give four examples of abiotic factors

Air, water, light, soil, pH, temperature, salinity,
humidity, inorganic nutrients.
3 - $300

What are the biological influences on organisms
called?

Biotic factors
3 - $400

Another word for consumer is ____________.

Heterotroph
3 - $500

What are the three methods used in ecological
studies?

Observation, experimentation, and modeling
4 - $100

What determines an ecosystems carrying
capacity?

Limiting factors
4 - $200

These operate strongly when population density
reaches a certain level.

Density – dependent limiting factors
4 - $300

These affect all population in similar ways,
regardless of population size and density.

Density-independent limiting factors
4 - $400

Name three density dependent limiting factors.

Competition, predation, herbivory, parasitism,
disease, stress from overcrowding
4 - $500

Around 80 deer
5 - $100

This can be described as a network of feeding
interactions.

A food web
5 - $200

These organisms break down organic matter.

Decomposers
5 - $300

Each step in a food chain or food web is known
as a ___________________.

Trophic level
5 - $400

What term describes the total amount of living
tissue within a given trophic level?

Biomass
5 - $500

This illustration is used to show the relative
amount of energy or matter contained within
each trophic level in a given food chain or food
web.

Ecological pyramid
