The number of different species of plants and animals in an area.
Biodiversity
Describe how introducing a non-native species of an animal can reduce an area’s biodiversity over time.
Cause damage or kill native species of animals or plants
An ecosystem with high biodiversity has what?
Large variety of plants and animals
On or of Earth
Terrestrial
A system comprising all the biotic and abiotic factors in an area and all the interactions among them.
Ecosystem
What is the benefit of having a variety of pollinating birds and insects, and how could this service be harmed by changes in their population?
Insects and birds that help pollinate can benefit plants that depend on pollinators to produce food.
Changes in their population could result in fewer pollinators and fewer crops produced for food.
How does changing an ecosystems biodiversity effect humans?
We depend on the natural resources the ecosystem provides.
What color would represent the most biodiversity?
Dark green, Tropical Rain Forest
Proper disposal of used resources so they can be reprocessed into new products.
Recycling
What factor contributes the most to the overall health and sustainability of an ecosystem?
The biodiversity in the ecosystem
The chart below lists data on four different projects designed to restore a wetlands habitat destroyed by human activity and a recent hurricane. Which project would be the best choice?
Project 3
The process of removing undesirable chemicals and contaminants from water.
Water Purification
A source or supply that benefits organisms.
Resource
How do humans benefit from ecosystems?
Food, shelter, water
Nitrogen pollution enters fresh water due to a variety of pesticides and fertilizers. This has a negative effect on plant and animal life. Certain plants however are able to purify the water back to the non polluted state. What would increase the negative effects of nitrogen pollution?
Loss of the plants able to purify the water due to biodiversity levels decreasing.
What are some factors that would benefit biodiversity levels?
A larger number of plant species
means a greater variety of crops.
Healthy ecosystems can better
withstand and recover from a
variety of disasters.
A group of organisms with similar characteristics that are able to interbreed or exchange genetic material.
Species
If you cut down a forest for a new highway, what can you predict will happen to the overall health and sustainability of the ecosystem over time?
The ecosystem will begin to decline due to the removal of native organisms.
Are there examples of ecosystems that thrive with low biodiversity levels? If so what is an example?
Yes, desert and tundra
What are some factors that would harm biodiversity levels?
Pollution
Food waste
Extinction
