- 2. Where Do Living Things Live??? Living things need a place to live and grow.
- 3. Fish live in water.
- 4. Birds live in trees and fly through the air.
- 5. Plants grow where there is soil, water and sun.
- 6. Habitat is a place where plants and animals lives.
- 7. Different types of organisms live in an ecosystem. A group of organisms of the same kind living in the same place is a population.
- 8. Main Idea and Details Living things need a place to live and grow. Fish live in water. Birds live in trees and fly in the air. Plants grow where there is soil, water and sun.
- 9. ENVIRONMENT The living and nonliving things that surround a living thing make up its environment.
- 10. What do living things get from their environments? Many living things share their environments and its resources. 1. Food 2. Water 3. Oxygen 4. Space
- 11. Parts of an Ecosystem An ECOSYSTEM is made up of all the living and nonliving things in an environment. Ecosystem is a system of living things that interact with each other and with the physical world.
- 12. All the population that live in an ecosystem at the same time form a community.
- 13. All members of a community live in the same ecosystem but they do not all live in the same part of the ecosystem.
- 14. It is a place where they can meet their needs. Animals get food, water, and shelter from their habitat,
- 15. Organisms and their Habitats Some organisms can survive only in certain habitats. For example, a polar could not find the water it needs in a desert.
- 16. COMPONENT OF ECOSYSTEM BIOTIC (Living things) ABIOTIC (Non Living Things) Air Rocks Cave Soil water Fish Water lily Plants Animals People
- 17. Use the following tree map to write a lesson summary. Parts of an Ecosystem Populations Communities Habitats
- 19. All energy comes from the sun Plants harness the sun’s energy in which process?
- 20. Plants need light for photosynthesis, what else do they need? We call plants producers because they produce energy from the sun directly.
- 21. Many animals eat only plants-they are vegetarians. We call animals that eat plants primary consumers
- 22. The next group, called the secondary consumers are carnivores or omnivores. They eat the primary consumers.
- 23. A Basic Food Chain Plants absorb light from the sun, which is turned into energy to grow. We call these producers. The vegetarian animals eat the plants, they are called primary consumers. Secondary consumers prey on primary consumers.
- 24. What is a food chain? A food chain is “a sequence of organisms, each of which uses the next, lower member of the sequence as a food source1”
- 25. Sort these animals into a food chain.. Can you think of a food chain of your own?
- 26. Energy flow in food chain Where do living organisms obtain their energy to live from? SUN • If plants are eaten by 1st level consumer, the energy is transferred to the 1st level consumer • If 1st level consumer is eaten by 2nd level consumer, the energy is transferred to the 2nd level consumer • And so on…
- 27. What is a food web? A food web is an interlocking pattern of food chains
- 28. ECOLOGICAL PYRAMID Definition: A graphical presentation of the relationship between different organism in an ecosystem based on who eats whom and also represent the flow of energy
- 29. TYPES Pyramid of numbers The number of each species in the food chain in a habitat is estimated Pyramid of biomass The amount of matter in a body is found by drying it to remove all water and then using scales to find the mass.
