The study of relationships between organisms and their environment.
Ecology
Both organisms benefit.
Mutualism
What are the four basic needs of living things.
air/gas exchange, water, food, and shelter/habitat
Humans clear forests to build roads, farms, or communities. What is one impact this can have on wildlife?
Loss of habitat
Resources replaced naturally over time.
renewable resources
The place where an organism lives.
Habitat
One benefits, one is unaffected.
commensalism
Living things must do this to ensure survival of their species.
Reproduce
Which would harm a wetland less: a road through it or an elevated bridge over it and why?
Elevated bridge over it so you are not destroying any ecosystems.
Name three natural resources.
Water, oil, minerals, trees, etc.
An inherited characteristic that helps an organism survive.
Adaptation
One benefits and one is harmed.
parasitism
The two main types of adaptations studied in class.
structural/physical and behavioral
Name two ways humans can help protect or restore ecosystems.
Examples include controlled burning, conservation, reducing pollution, protecting habitats, recycling resources, or creating wildlife corridors.
True or False: Humans are the only organisms that use natural resources.
False
A person who studies the enviroment.
Ecologist
A clownfish and sea anemone relationship.
Mutualism
A bear's thick fur is this type of adaptation
Physical/structural
Why do ecologists study ecosystems before major construction projects begin?
To predict and reduce environmental impacts.
The difference between a need and a want.
A need is required for survival; a want is not.
Two species living closely together over time.
Symbiosis
The organism harmed in a parasitic relationship.
Host
Migration is this type of adaptation.
Behavioral
A company wants to cut down a large area of forest to build houses. Give one benefit to humans and one negative impact on the ecosystem.
Benefit: housing/jobs. Impact: habitat loss, reduced biodiversity, disrupted food webs, etc.
Cutting down forests decreases this gas in the atmosphere.
