Define Natural Resource

materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.

Define Pollution

The act or process of polluting or the state of being polluted, especially the contamination of soil, water, or the atmosphere by the discharge of harmful substances

Define recycling

to treat or process so as to make suitable for reuse

Define Conservation

preservation, protection, or restoration of the natural environment, natural ecosystems, vegetation, and wildlife.

Define limiting Factor

an abiotic or biotic factor that restricts the number of individuals in a population. 

Give an example of at least 3 limiting factors

1.Competitors 2.Disease and parasites 3.Natural Disasters 4.Available habitat 5.Predators

Define Carrying Capacity

the maximum number of individuals of a species that an ecosystem can support.

What is an ecosystem?

all the living organisms that live in an area and the nonliving features of their environment

List at least 1 way humans affect the environment negatively and give one solution. 

Methane production Air pollution Deforestation  Ocean Acidity  Pollution

List one way that humans affect the environment positively.

Recycle Carpool Eat less meat Use less paper Turn off lights 

Name one reason a population may increase

Less predators More resources  Positive human impact 

Name one reason a population may decrease

Negative human impact Natural disasters Disease Parasites Increase of predators Decrease in resources

Give an example scenario of comeptition

A zebra and giraffe must compete to drink the same water from a watering hole in the African Savanna 

What is the carrying capacity of this graph?

1,000 organisms 

If the prey increases, what will happen to the population of the predator?

The population of the predator species will also increase

True or False: Limiting factors can sometime be beneficial to an environment? Please explain your answer.

True. Limiting factors allow for population of species to be below the carrying capacity. 

What limiting factor reduces the population of rabbits in the winter, but not the spring?

Cold weather or decline in natural resources such as food source. 

What would happen to an ecosystem if the population of mosquitos declined rapidly?  Mosquitos are primary consumers.  

The producers would increase, predators would decrease
