Maddie Mulhall's Mind Map Vocab Project

Levels of Organization


Any form of life


Group of the same species located in the same area.


Populations of living organisms interacting with one another.


Group of organisms interacting with living and nonliving things


Geographic region of Earth that is inhabited by a community of plant and animal species


Layer of soil, water, and air that sustains life

Biotic Factors

The living parts of an ecosystem  

Abiotic Factors

The nonliving parts of an ecosystem

Trophic Levels

Trophic means energy

Producers (Autotrophs)

Produce their own energy.

Primary Consumers

Eat producers (1st degree consumer

Secondary Consumers

Eats 1st degree consumers (2nd degree consumers)

Tertiary Consumers

Eats 2nd degree consumers (3rd degree consumers)

Food Chain

Food chains show the sequence of energy transferred from one organism to the next as one eats the other.

Food Chain Rules: a. Focus on one ecosystem at a time b. Chose an organism at each level that would actually eat the one before it c. Always think about the direction the arrows should be going (where the energy is going)


Biodiversity is the variety of organisms in a geographic area that provides us, as humans, with essential natural resources like food, fibers for clothing, and medicine.


Population growth is the increase of a species in an area

Black Plague

A wide spread disease in the 1400's that was the largest decrease in human population ever recorded

Industrial Revolution

Main cause of the worlds population in the 1800's

Advancements from this time period include: agricultural revolution, food production, medicine advances, sanitation advances, and nutrition advances

Exponential Growth

Exponential Growth is a rapid growth or a constant growth rate (J-curve)


The capacity to endure

Logistic Growth

When the growth rate goes up and down as time passes



Population Growth Rate

The change in population over time



Temperate Deciduous Forest

Coniferous Forest




Freshwater Biome

Marine Biome

Hot Spots

Biodiversity hot spots are biogeographic regions with a significant reservoir of biodiversity that is under threat from humans and are mostly found in the tropics by the equator.

There are more than 17 regionsof hot spots that cover almost 2% of Earth's land area

Food Webs

Shows what an ecosystem looks like; whole bunch of food chains

Ecological Succession

Ecological Succession is a series of enviromental changes

Primary Succession

Growth of plants and animals in a place with no enviroment

Events that cause this type include growth of the side of a volcano and a landslide

Secondary Succession

Growth of plants and animals after something destroys life

Events that cause this type include a fire and deforestation

Pioneer Species

The first species to move into an area

Example: Lichen or moss

Climax Community

A climax community begins to form at the final stage of succession

Example: Grasses in prairies of cacti in deserts

Limiting Factors

The conditions of the enviroment that limit the growth of a species

Examples: water, energy, shelter, sunlight, predators, food, minerals, nutrients, competition, disease, etc.

Carrying Capacity

The number of individuals of a species that an ecosystem can support

Limiting factors control the amount of species in an ecosystem and keeps them at finite capacity, or carrying capacity

Water Pollution

Water pollution is the contamination of water, by sewage effluent, fertilizer runoff, industrial chemical discharge etc

Point Source

Pollution that comes from a single source  

Ex: Factory or waste water treatement plant

Non-point Source

A large amount of water pollution that does not come from a single point, but from many different sources

Ex: Fertilizer, pesticides, pet waste, motor oil, household hazardous wastes, and/or driving a car


Any geological formation containing water, especially one that supplies water for wells and springs. It is similar to an underground river.
