This is a biosphere powerpoint I've created for a middle school level science class. It's full of fun animated cartoons and facts on both aquatic and terrestrial biomes.

The biosphere
1. THE BIOSPHERE Let’s join our animal friends around the world and explore all the Earth’s Biomes from the tallest mountains to the deepest depths of the sea.
2. Aquatic Biomes Lakes This is any standing body of water and can range from tiny ponds to much larger lakes. The temperature ranges due to the decrease in light with the increase in depth. Some common organisms found in lakes are: -Photosynthetic which means they need sunlight to make their own food. Examples: Rooted and aquatic floating plants -Other organisms are called heterotrophs which cannot make their own food and rely on eating other substances. Examples: simpler organisms like Zoey zooplankton and her friends, various invertebrates and fish.
3. Lakes Oh yea, we can lay back and eat as much phytoplankton as we want. You know we also eat other zoo plankton. .. Boy do I like to float on the surface where it’s all warm and bright. Uh -oh
4. Aquatic Biomes Wetlands Any inundated areas which are areas saturated with water at least some of the time. 3 kinds: Basin wetlands-in shallow basins Riverine wetlands- along shallow streams & rivers Fringe wetlands- along coasts of big lakes and/or seas Organisms Photosynthetic- plants like cattails that can grow in water and in soil Heterotrophs- invertebrates, birds, herbivores (plant eaters) & carnivores (meat eaters) like Alfred the alligator.
6. Aquatic Biomes Streams and Rivers Bodies of water with a current River bottoms are coated with sediments Organisms Photosynthetic- in some warmer climates like the desert and savanna, the headwaters have many aquatic rooted plants and phytoplankton Heterotrophs-fish and invertebrates like Tina the trout
8. Aquatic BiomesEstuaries &Intertidal zones Estuaries-The area that transitions between the rivers and seas and can be salt and/or fresh water. Organisms Photosynthetic- grasses, algae, and phytoplankton. Heterotrophs- invertebrates, fish, worms, and crustaceans (like cliff the crab!) etc. Intertidal zones- when a shore is under water part of the time and exposed to the air for the rest. May be rocky or sandy Organisms Photosynthetic-marine algae and sea grass Heterotrophs- organisms that attach to rocks or burrow such as sea sponges, crustaceans, worms and small fish.
9. Estuaries & Intertidal Zones Intertidal Zones Estuaries I can live in both of these places, but my favorite is the intertidal zones! I just love to burrow!
10. Aquatic Biomes Ocean Pelagic & Coral Reefs Ocean Pelagic means a huge body of open water. Organisms Photosynthetic- phytoplankton, photosynthetic bacteria Heterotrophs- zooplankton, protists, small invertebrates, and fish as well as squids, fish and marine mammals (like Wallace the Dolphin). Coral Reefs are actually skeletons of coral found near islands, or along the coasts of continents. Organisms Photosynthetic- unicellular, red, and green algae Heterotrophs- coral, fish like Carl the Clownfish, and invertebrates.
11. Ocean Pelagic & Coral Reefs Ocean Pelagic Coral Reefs Hey did you know the ocean covers 70 percent of the world!? Yikes a shark!
12. Thanks for exploring the Aquatic Biomes with us!Now we're going to move onto land and discover the Terrestrial Biomes.
13. Terrestrial Biomes Tropical Rainforest Precipitation- A lot of rainfall (about 200-400cm on average). Temperature- Hot and humid all year round Plants- Characterized by canopy trees with many layers, shrubs, and broadleaf trees. Animals- huge variety of biodiversity including amphibians, birds, reptiles, mammals, insects, spiders, etc. This is the home of amphibian, Trudy the Tree Frog.
14. Terrestrial Biomes Desert Precipitation- low (less than 30 cm per year) Temperature- varies between seasons and day and night Very cold at night and scorching during the day. 50 degrees Celsius to negative 30 degrees Celsius Animals Snakes, lizards, beetles (like Bernie), birds, and rodents. Plants Scattered with small vegetation, and succulents (like cacti) It may look boring, but just wait until nighttime. All the critters come out and play because most of us are nocturnal.
15. Terrestrial Biomes Savanna & Temperate Grasslands Savanna Precipitation- seasonal rains and periodic droughts Temperature- generally warm (24-29 degrees Celsius) Plants Scattered trees and grasses Adapted to dryness and fires Animals Large Herbivores (like Billy Bison) and antelope Predators (lions and hyenas) Insects Grasslands Precipitation- seasonal (dry winters and wet summers) Temperatures- ranges with cold winters and hot summers. Plants Grasses and forbs (also fire and drought resistant) Animals Large grazers (bison and wild horses) and burrowing mammals. Hey there! I’m Billy Bison and I can’t wait to show you my homes!
16. Savanna and Temperate Grassland Of course both of these biomes are very similar and both have yummy grasses for me to munch on. Temperate grassland Savanna
17. Terrestrial Biomes Coniferous & Temperate forests North Coniferous Forests Temperature- Cold, long winters and hot summers Precipitation- 30 to 70 cm with occasional droughts Plants Cone-bearing trees (conifers) Examples: Spruce and pine trees Animals Large mammals such as bears and moose like Morty! They also have migratory birds Temperate Forests Like what we have here in Michigan Precipitation is constant through all seasons Temperature- winters are cold and summers are hot ranging from 0-30 degrees Celsius. Plants Distinct layers like the rainforest (canopy, understory, and shrubs) Deciduous trees like Oak and Maple. Animals Mammals that hibernate like bears and birds that migrate and fly south for the winter.
18. Coniferous and Temperate Forests Temperate forest Marty says: I prefer the coniferous forests, but when the fall rolls around in temperate forests those trees are bea-u-t-ful. Coniferous Forests
19. Terrestrial Biomes Tundra Precipitation is generally only 20-60 cm annually Temperature- The winters are long and cold followed by short cooler summers. Animals Large grazing animals like oxen, caribou, and reindeer Predators like wolves and foxes much like Ferdinand Migratory birds Plants Mosses, grasses, forbs, lichens
20. Tundra The tundra can be beautiful and flowering, but it can also be covered in snow! In the winter my coat even changes color so that I can blend into my surroundings and hide from predators.
21. And that wraps up all the biomes!Thanks for joining us on our big exploration!
