LT: I can explain why biodiversity is important.


Notes: What is Biodiversity?
Biodiversity= # of species (richness)/ # of individuals (abundance)

Species Richness=# of species (fox, moose, robin)=3

Species Abundance=# of individuals of each type of species (2 fox, 1 moose, 5 robins)=8
Biological diversity: the variety, of plants and animals and other living things in a SPECIFIC area or region.
*For instance, the species that inhabit Los Angeles are different from those in San Francisco, and desert plants and animals have different characteristics and needs than those in the mountains, even though some of the same species can be found in all of those areas.

Biodiversity also means the number, or abundance of different species living within a particular region.

In practice, "biodiversity" suggests sustaining the diversity of species in each ecosystem as we plan human activities that affect the use of the land and natural resources.

Why is biodiversity important?
Everything that lives in an ecosystem is part of the web of life, including humans. Each species of vegetation and each creature has a place on the earth and plays a vital role in the circle of life. Plant, animal, and insect species interact and depend upon one another for what each offers, such as food, shelter, oxygen, and soil enrichment.

Part 1: Why is Biodiversity Important?
Habitats that have a greater variety of different species of plants and animals have a greater biodiversity. These habitats are also healthier and more stable. One reason diverse communities have greater levels of health is that organisms of the same species tend to be more spread out. This reduces the ability of a disease to spread throughout a habitat. Additionally, if a certain type of species of tree or plant does become infected, the other species will remain and continue to provide the habitat components for the organisms in that area.

In an area consisting of monoculture, an area with only one type of plant species growing, the plants are more susceptible to disease and other stresses because they are all the same and less spread out (no other types of plants between them). As a result, [the entire habitat can be dramatically altered when impacted by disease or other stresses]. Human-made monocultures (crops, etc.) are created to make harvesting easier. However, they typically require larger amounts of pesticides and herbicides (to prevent diseases and/or “weeds”) and larger amounts of energy and labor to maintain before harvesting.

Based on the reading, what are two reasons biodiversity is important?

2.


How do I calculate the biodiversity in an area?

Biodiversity= # of species (richness)/ # of individuals (abundance)

Species Richness=# of species (fox, moose, robin)=3

Species Abundance=# of individuals of each type of species (2 fox, 1 moose, 5 robins)=8


EXAMPLE

# of species (fox, mouse, rabbit, elk, bald eagle)
5
# of individuals
--1 fox
--5 mice
--2 rabbit
--1 elk
--1 bald eagle
10

Biodiversity=5 species/10 individuals= 0.5

Let’s look at the table below and figure out the Species Richness and Species Abundance for Field A and Field B.

Practice Together:


Field A
Field B
Animal Species Richness
Mice, hare, bees, ants, beetles, voles
Beetle
Animal Species Abundance
Mouse-20, hare-15, bees-45, ants-100, beetles-75, voles, 35
Beetle-300


*Field A Species Richness=__________________________________

*Field A Species Abundance=_______________________________


*Field B Species Richness=_________________________________

*Field B Species Abundance=______________________________


Now let’s figure out the Diversity Index…


Pine Forest
Rainforest
Plant Species Richness
20
100
Plant Species Abundance
102
455


*Pine Forest Diversity: ______________________________________________________=

*Rainforest: ______________________________________________________=

*The closer to 1.0 it is, the higher the biodiversity.*

--Which has more biodiversity, the pine forest or the rain forest? How do you know?

With a partner….


Field A
Field B
Animal Species Richness
Crow, squirrel, rabbit
Moose, deer, coyote, mice, dragonfly, Canada goose
Animal Species Abundance
Crow-5, squirrel-10, rabbit-6
Moose-2, deer-10, coyote-12, mice-55, dragonfly-30, Canada goose-20


*Field A Species Richness=__________________________________

*Field A Species Abundance=_______________________________

*Field B Species Richness=_________________________________

*Field B Species Abundance=______________________________
Now let’s figure out the Diversity Index…


Grassland
Desert
Plant Species Richness
25
15
Plant Species Abundance
275
275


*Grassland: ______________________________________________________=

*Desert: ______________________________________________________=


--Which has more biodiversity, the grassland or the desert? How do you know?

By Yourself!


Forest Plot A
Forest Plot B
Animal Species Richness
Gorilla, mandrill, scorpion, ants, beetles, python, rainforest bird
Gorilla, mandrill, scorpion, ants, beetles
Animal Species Abundance
300
250


*Forest A Species Richness=__________________________________

*Forest A Species Abundance=_______________________________


*Forest B Species Richness=_________________________________

*Forest B Species Abundance=______________________________


Now fill in the chart below and figure out the Diversity Index for the numbers you have from the above problem…


Forest A

*Forest A: ______________________________________________________=

*Forest B: ______________________________________________________=



--Which has more biodiversity, Forest A or Forest B? How do you know?

Respiration vs Photosynthesis Notes

Cellular Respiration:
Cellular respiration is a complex series of chemical reactions that harvests the energy trapped in the bonds of glucose sugar molecules and converts it into a chemical form that can be stored for later use.

Humans and other animals obtain glucose sugar molecules from food, such as the fruits and grains

**Essential to the survival of most organisms on Earth, cellular respiration yields the energy that makes our bodies function properly.

Photosynthesis:
Plants create glucose sugars in the process of photosynthesis, by converting sunlight into glucose
