Biodiversity PowerPoint Notes
Name:
Essential Question: What are the types of biodiversity and why are they important?
Biosphere
The __________________________ is the sum of_______________________________________in the five kingdoms
 Animals, Plants, Bacteria, Protists, Fungi
 Scientists believe that life on earth began about _________________________________________
Biodiversity is the_______________________________________________________
There are ________ types of biodiversity:
 Species Diversity: variety of Species
 Ecosystem Diversity: variety of ecosystems
 Genetic Diversity: variety of genes (traits) in a population
 Functional Diversity: variety of ecological roles organisms play
Species diversity describes:
 _______________________________present in an ecosystem
 ________________________ of species within an ecosystem
 To date, scientists have identified over __________________________ of species on Earth.
You can calculate and compare the biodiversity of ecosystems by using the biodiversity index formula:
Biodiversity Index = Number of Species / Number of Organisms
A biodiversity _________________is a biologically rich region that is an irreplaceable reservoir of _____________ diversity.
 Hotspots are threatened with destruction
 Hotspots contain _____________________species
 Only approximately 2.3% of Earth’s land surface is a hotspot
 Hot spots contain species found nowhere else on the planet
Genetic diversity is the ____________________________________found in a population or in a species.
 Traits, determined by genes, are passed on from parent to offspring.
 Variations in traits contribute to genetic diversity.
 Species have a better chance of _______________and ________________to _____________________________
 Increased chance that individuals will have favorable traits needed to survive and resist disease.
Ecosystem diversity is the ________________________________________________________________in a given place.
 An ecosystem is a community of organisms and their physical environment interacting together.
 A ____________________is a collection of ecosystems with similar climate and species.
 Ex. Tundra, Rainforest, Desert, Grassland
Functional diversity is the __________________________________such as energy flow and matter within ecosystems.
 Concern the _______________________________________organisms play in their communities and how these roles
impact the ecosystem overall.
o Examples:
 How an organism fits into the food chain
 Feeding strategies (grazers, predators, scavengers)
 How organism behavior affects abiotic factors in the ecosystem
If more than one species ________________________________, or functional trait, the ecosystem will be ___________ to
withstand some species lost without losing functionality.
If an ecosystem has few species, with different functional traits, species loss with have a greater impact on the functionality of
the system.

Biodiverse Ecosystems Are:
 __________________________
 Have increased biomass (more producers)
 __________________________
 __________________________
 __________________________to negative impacts and disease
The Insurance Hypothesis:
 Biodiversity ensures ecosystems against a decline in their functioning because ________________________________
________________________________________________________________________________________________
Biodiversity _____________________________________________________________________
 Air and water purification
 Soil renewal
 Decomposition of waste
 Pollination
Biodiversity supports provides humans with:
 __________________________
 __________________________
 Building Materials
 Fuels
Biodiversity Supports Evolution
 Genetic diversity provides the materials for the _________________________________and ecosystem services
 Through evolution, species are able to respond and _________________________________________________
Humans have long impacted biodiversity.
Deforestation
Over-hunting and Over-fishing
Climate Change
Urban Development
Habitat Fragmentation

Pollution
Pesticides and Herbicides

You Make a Difference!
Reduce, Reuse, and Recycle
Tell others to be good to the Earth.
Don’t pollute
Use less water
Clean up litter
Drive less
Watch out for plants and animals
Vote for politicians who support the environment
Buy locally grown and raised foods
Try to make your use of natural resources less than your need for them.
