Ecosystems Daniel and Alejandro

  1. 1. ECOSYSTEMSECOSYSTEMS
  2. 2. ECOSYSTEMSECOSYSTEMS ORGANISATIONORGANISATION ECOSYSTEM Marine: ecosystems are one of the largest ecosystmes on Earth. They include differents types of ecosystem such as kelp forest, corals reefs, shorelines and open oceans. Marine ecosystems have mammals and many different species.
  3. 3. HABITATHABITAT • Habitat is a place where an organism lives. • A habitat is very variade.
  4. 4. POPULATIONPOPULATION Population is called when organisms of the same species interact within them. They live bacteria, algae and types of plakton.
  5. 5. COMMUNITYCOMMUNITY Different population interact with each other in communities. They lives differents species of fish, mammals and invertebrates living together.
  6. 6. TROPICAL REINFORESTTROPICAL REINFOREST
  7. 7. DEFINITION Form the most diverse ecosystem on land. They have the Amazon, Congo Rivers and The Islands of Indonesia
  8. 8. 1.EMERGENT LAYER1.EMERGENT LAYER •Emergent trees are usually about 50 or 60 metres tall. These trees have adapted to survive in hot temperatures and strong winds.
  9. 9. 2.CANOPY LAYER The trees in the canopy layer are often more than 30 metres tall. Birds, mammals, insects and reptiles all live up here. Many never leave the treetops and spend their whole lifecycle in the canopy.
  10. 10. 3.UNDERSTORY LAYER This is the part of the forest made up of trunks, branches, bushes and shrubs. Predators like jaguars and snakes live in this section, along with small mammals, amphibians and reptiles.
  11. 11. 4.FOREST FLOOR4.FOREST FLOOR This part of the forest belongs to invertebrates, fungi and bacteria, most of which live on the decomposing matter that comes from the animals and trees above. The forest floor is dark as little sunlight penetrates though the canopy.
  12. 12. TUNDRA
  13. 13. DEFINITION • The tundra is an ecosystem with low temperatures and no light for half the year. The most common plants are mosses, lichens and some grasses. Tundra is sparsely inhabited and the cycles of growth and decomposition take place at a much slower rate than in other ecosystems.
  14. 14. FOOD CHAINFOOD CHAIN
  15. 15. DEFINITIONDEFINITION • It’s made up of three levels: • Producers (plants, sun…) • Consumers: primary, secudary and terciary consumer. • Decomposers: Feed on other death organisms.
  16. 16. FOOD WEBFOOD WEB
  17. 17. DEFINITIONDEFINITION • There is an interdependence of species wich live off each other. • The interdependecies form Food Webs. • Are made up of different food chains. • Produce energy (Biomass) food for the next tropic level.
