Biodiversity

Lesson 1: Review & Intro

Multiple Choice

Let's say Earth was hit with another asteroid (HUGE rock from space - liked what killed off many species 65mya). Looking at the images, which would more likely have some species that survive?

• A

• B

Open Ended

Today's lesson is focusing on how diversity amongst living things is important for survival. Sometimes being in middle school can feel like it is more important to be like everyone else, but today I want you to think about ways you are grateful for all the differences among people. Share an example of how you are different from another peer that brings you joy!

Multiple Choice

What is biodiversity?

• the number of species in one area

• the number of one type of species in one area

• the variety of life in our ecosystems

• the relationships in an ecosystem

Multiple Choice

Which ecosystem has a higher diversity?

• Community A

• Community B

• They are the same

Multiple Choice

Having more diversity allows organisms and environments to...

• Respond to changes better

• Evolve and Adapt at a slower rate

• Become extinct

• All of these are correct

Review of Terms

Multiple Choice

An ecosystem contains living and nonliving things.

• True

• False

Multiple Choice

What is it called when you have groups of different populations along with their abiotic factors?

• An organism

• A population

• A community

• An ecosystem

Multiple Choice

Together, all the ecosystems on Earth form...

• a community.

• a biome.

• a biosphere.

• an Earthsphere.

Multiple Choice

What are groups of different populations living togther in the same place at the same time called?

• An organism

• A population

• A community

• A biosphere

Multiple Choice

A group of the same organisms living together in the same place at the same time is:

• An organism

• A population

• A community

• A biome

1. Genetic Diversity

• Genes come from your DNA that create you

• You are born with DNA - half from each parent, but environment can also affect your DNA

• Variety within a species is key for species survival

• For example if a rare disease destroyed all red apples, there are many other apples would still survive.

Multiple Choice

Which is NOT an example of genetic diversity in humans?

• hair color

• height

• skin color

• stomach

2. Species Diversity

• The number of species & the population size of each species in a particular location

• More species = larger food web = more food options

• More food options = better chance for species survival

Multiple Select

Species diversity includes:

• The number of species

• The amount of each species

• The different genes within a species

• The ways different species interact

Closer to the Equator = More Species Diversity

• Tropical Rainforest is 6% of the land

• 50% of Known Species are Found at the Tropical Rainforest

• Therefore - Highest species diversity is found here!

Multiple Choice

Which biome likely has the least diversity?

• Alpine Tundra

• Temperate Forest

• Savannah or Grasslands

• Tropical Rainforest

Multiple Choice

Which biome has the most diversity?

• Alpine Tundra

• Temperate Forest

• Savannah or Grasslands

• Tropical Rainforest

3. Ecological Diversity

• The variety of ecosystems - terrestrial & aquatic

• Examples of ecosystem diversity for aquatic: wetlands, oceans, freshwater

• Within each ecosystem are the varieties of roles - producers, herbivores, consumers etc.

Multiple Choice

Define ecosystem diversity

• variety of ecosystems in a given area

• variation of genes within a species or population in a given area

• variety of life in Earth's land, freshwater, and marine ecosystems

• changes to an ecosystem that affect how the parts of it interact

Multiple Choice

 Which biome is more likely to survive a change in the environment?

• High (rich) biodiversity

• Low (poor) biodiversity

Multiple Choice

Why is biodiversity important in fighting disease in food crops?

• It prevents one disease from wiping out an entire food crop.

• It prevents habitat loss of native species.

• It provides different foods for different populations.

• It prevents fungal disease from wiping out corn crops.

Multiple Choice

Food Web B is an example of...

• Low biodiversity and low sustainability. If the producer dies then all the food web will suffer.

• High biodiversity and high sustainability. If an organism is removed the food web will continue with no effect.

Multiple Choice

Why is biodiversity so important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well

• Because it’s better to have only one variation of each species.

• Because it better to only have a few species on Earth.

• Because my teacher needs lots of chocolate options to keep her from being cranky!

Poll

What are concepts are you comfortable with?

• Defining biodiversity

• Defining the 3 key types of biodiversity

• ID examples for 3 types of biodiversity

• Explaining the importance of biodiversity

Poll

This is trial 1 of making you do notes as you do the lesson. Please mark all the statements you agree with. I am doing multiple trials, so your response will only affect my students for next year.

• The notes were short and easy to fill in.

• It forced me to slow down a little on the lesson & pay more attention.

• I did better on the questions as I had the notes to use

• I didn't find the notes helped me today.

• The notes though short, took me too long to complete

Minimum Score = 90%

Please retake until you score a 90%. Make sure you are feeling comfortable with the concepts. If there is plenty of time in class, go for the 100% as it is good for your brain. You've got this!
