What Does an Organism Get from Its Environment?

1. What Does an Organism Get from Its Environment? • An organism gets food, water, shelter, and other things it needs to live, grow, and reproduce from its environment. • An environment that provides the things an organism needs to live, grow, and reproduce is called its habitat. • Organisms with different needs live in different habitats.

2. What Are Two Parts of an Organism’s Habitat? • Biotic factors are the living or once living parts of a habitat. • Abiotic factors are the nonliving parts of a habitat. • Sunlight • Soil • Temperature • Oxygen • Water Ecosystem: The community of species that live in an area, along with the abiotic factors in the area

3. So how is a Biome different from an Ecosystem or Habitat? • Habitat: the area or environment where an organism or ecological community normally lives or occurs. • An Ecosystem: a system formed by the interaction of a community of organisms with their physical environment. It includes many habitats and living and non-living things. • A Biome is a major regional grouping with similar climate, plants, and animals.

4. Levels of Organization in an Organism’s Environment • From smallest to largest, the environmental levels are: • Organism or Individual: A single living thing • Population: A group of organisms of the same species living in a particular area • Community: All the different species that live together in an area • Ecosystem: The community of species that live in an area, along with the abiotic factors in the area

5. How Is an Ecosystem Organized?

6. What in the world is a biome?! • Scientists have developed the term Biome to describe areas on the earth with similar climate, plants, and animals. • Biomes are made up of • several ecosystems

8. How is a biome different than an ecosystem or a habitat? • Habitat: the area or environment where an organism or ecological community normally lives or occurs. • Think of yourself as the organism. Your house is your habitat, but your community (all the people, and animals in your area) is Lost Creek Ranch or the City of Allen (depending on how much area you want to include). So that is like one big habitat.

9. How is a biome different than an ecosystem or a habitat? • An Ecosystem: a system formed by the interaction of a community of organisms with their physical environment. It includes many habitats and living and non-living things. • Your ecosystem would be more like the state of Texas or the southwest United States and it would include the land and water here not just the people and animals.

10. How is a biome different than an ecosystem or a habitat? • A Biome is a major regional grouping with similar climate, plants, and animals. • Your biome would be the United States. • There are many different types of Biomes! • Let’s look back at our classification pyramid in a different way now.

12. Biomes of the World A journey across the Earth in 30 minutes…

13. What biomes are on Earth? • Scientists can’t agree on exactly how many biomes Earth has!! One scientist pictures the biomes like this:

14. The North Western Hemisphere • Let’s take a closer look at where we live…

15. Another way to look at it…

16. Let’s take a closer look at some specific biomes…

17. Aquatic Biomes: • Water: Submerged • Temperature: Varies • Soil: None • Plants: Aquatic Plants (seaweed) • Animals: Fish, Shelled fish, invertebrates (animals with out backbones), select mammals.

18. Aquatic Biome

19. Tropical Rainforest • Water: Very wet • Temperature: Very warm • Soil: Poor, thin soil • Plants: Many plants (trees, flowers, shrubs, etc.) • Animals: Many animals (birds, mammals, reptiles, insects, etc.) Many endangered species with a lot of competition for resources. • Near the Equator

20. Rainforests

21. Tundra • Water: Dry • Temperature: Cold • Soil: Permafrost (frozen soil) • Plants: Lichens and mosses • Animals: Migrating animals, and small rodents • Located near the North Pole.

22. Tundra

23. Taiga(also know as the Boreal Forest) • Water: Adequate • Temperature: Cool (year round) • Soil: Poor, rocky soil • Plants: Conifers (pine trees – evergreen trees) • Animals: Many mammals, birds, insects, arachnids, etc. • Far Northern regions just south of the Tundra

24. Taiga

25. Grassland • Water: Wet season, dry season • Temperature: Warm to hot (but often has a cold season) • Soil: Fertile soil • Plants: Grasses (few or no trees) • Animals: Many mammals, birds, insects, arachnids, etc. • Located in Temperate Climate Zones

26. Grassland

27. Temperate Forest (Deciduous Forest) • Water: Adequate • Temperature: Cool season and warm season • Soil: Fertile soil • Plants: Deciduous trees (trees that loose their leaves), shrubs, ground cover • Animals: Many mammals, birds, reptiles, insects, arachnids, etc.

28. Temperate Forest

29. Desert • Water: Dry (almost none) • Temperature: Hot or Cold (one or the other) • Soil: Poor (sandy) • Plants: Sparse - succulents (like cactus), sage brush • Animals: Sparse - insects, arachnids, reptiles and birds (often nocturnal)

30. Desert

31. Summary • What is a biome? • Name some of the world’s biomes… • What might location in the world (latitude and longitude) have to do with a biome?
