1 Warm Up 1.How does population affect the world’s resources? 2.What does the term “biodiversity” mean to you? 3.Make sure to turn in your homework! (Population Dynamics handout)

2 Objective & Agenda SWBAT Explain how abiotic and biotic factors interact to create the various biomes. 1.Biodiversity Notes 2.Video Analysis 3.Biotic vs. Abiotic Factors 4.How Humans are Involved & Solutions 5.Global Biomes & practice 6.Exit Ticket Lots of VOCABULARY so HEADS UP

3 What is the biosphere? The biosphere is all life on Earth

4 Biodiversity A measurement of the variety of life (species) within an ecosystem LEARNING OBJECTIVE: We will learn the importance of biodiversity in ecosystems.

5 What is biodiversity? Bio means: life Diversity means: variety Put the two together, and you get or. Let’s take a look at what biodiversity looks like: http://www.guardian.co.uk/environment/gall ery/2010/oct/04/bi0diversity100-wildlife- gallery http://www.guardian.co.uk/environment/gall ery/2010/oct/04/bi0diversity100-wildlife- gallery life variety variety of life What is a BIOME?

6 Interdependence Every species is linked, directly or indirectly, with a multitude of others in an ecosystem. Plants provide food, shelter, and nesting sites for other organisms. For their part, many plants depend upon animals for help in reproduction (bees pollinate flowers, for instance) and for certain nutrients (such as minerals in animal waste products). All animals are part of food webs that include plants and animals of other species (and sometimes the same species).

7 Why is biodiversity important? While you watch this video, write down five key facts that you find interesting. http://www.youtube.com/watch?v=4O1AwrQpj K8&feature=fvsr

8 FAST FACT More than 67 % of Americans are considered overweight

9 Abiotic vs. Biotic Factors Both play an important role in biodiversity…but what’s the difference? Biotic Factors Abiotic Factors

10 Abiotic vs. Biotic Factors Biotic, meaning of or related to life, are living factors. Plants, animals, fungi, protist and bacteria are all biotic or living factors.

11 Abiotic vs. Biotic Factors Abiotic, meaning not alive, are nonliving factors that affect living organisms. Environmental factors such habitat (pond, lake, ocean, desert, mountain) or weather such as temperature, cloud cover, rain, snow, hurricanes, etc.

12 What is the difference between Abiotic & Biotic Limiting Factors?

13 Difference: Living vs. Non-living ***Similarity: Both Control Population!***

14 Both are important…It’s a balance! Biotic Factors Abiotic Factors

15 LIMITING FACTORS Limiting factors are things that are needed to survive. The availability of limiting factors controls the size of a population. EX: food, water, air, space, sunlight, nutrients

16 ABIOTIC LIMITING FACTORS Abiotic limiting factors are non-living things that control the size of the population. EX: water, oxygen, sunlight, temperature

17 BIOTIC LIMITING FACTORS Biotic limiting factors are living things that control the size of the population. EX: food, predators, disease

18 CARRYING CAPACITY Carrying capacity is the largest number of individuals (population) an area can support What would be the carrying capacity of your house?

19 Ecology is the study of plants and animals and the relationships they have to each other and to their natural environment An ecosystem describes the system where these relationships occur – Ecosystems are often similar to biomes Ecology

20 Benefits of Biodiversity to Humans Climate stability Genetic variety Undiscovered resources Richer soils New technology Natural resources

21 Pollution Deforestation Overfishing Habitat destruction Depleting resources Extinction How can we harm biodiversity? **Invasive species – a plant or animal introduced by humans**

22 Examples of invasive species:

23 The world is a global ecosystem – every aspect of it, both biotic and abiotic, is essential for the life of something on earth. When you remove one piece, and the whole thing may crumble. Summary:

24 How science is helping to conserve Biodiversity Studying species, ecosystems and their interactions with humans to learn about biodiversity, How biodiversity is changing and how we can conserve it. Making their findings available to policy makers to inform decisions about agriculture, fisheries, medicine, development and conservation. Initiatives such as Biodiversity Month are uniting scientists and the public to share information.

25 BIOME A biome is a group of ecosystems that have the same climate and similar organisms. Same climate (long term weather patterns) and organisms (plants/animals)= biome COMBINES BOTH ABIOTIC & BIOTIC FACTORS

26 Global Biome Stations Learn about how Abiotic & Biotic Factors Make up each of the 7 Complex Biomes: 7 stations X 4 minutes a piece = 28 minutes When finished practice using the independent practice on the back.
