What are the parts of an ecosystem? I will know some ecosystems in which organisms live and interact.

Ecosystems Ecosystem Habitat All the living and nonliving things in an area and their interactions Habitat Food Water shelter

Biotic Abiotic Living organisms in an ecosystem You animals Your mom Birds Bacteria Nonliving parts in an ecosystem. Air Water Soil Temperature sunlight

Types of Ecosystems Abiotic determine what kinds or organisms live there The living organisms need to be able to survive What abiotic factor effects this ecosystem?

Populations and Community Small groups that include one species Humans Oak trees Monarch butterflies All of the populations living together All of the different species working together Depend on one another https://www.youtube.com/watch?v=cIfpKL0brwQ

Coral Reef Warm, clear, shallow water Many different species live there Endangered Ecosystem http://www.youtube.com/watch?v=d4TrLRUqUs8 http://www.youtube.com/watch?feature=player_embedded&v=wbNeIn3vVKM#!

Review What is a population? What is a community? A group of organisms of one species that live in the same area What is a community? Made up of different populations in an area. What are two abiotic factors in a coral reef ecosystem? Water, sand, rocks, water, sunlight

Tropical Rain Forest Warm and Rainy Lots of moisture in the air Many trees and flowers grow there, but not grass http://www.youtube.com/watch?v=Mv-yWsoPrSs

Desert Little Rain Hot Days Cool Night Extreme temperatures Some plants store water Rest during the day Big ears

Tundra – “treeless plain” No trees EXTREMELY cold weather Little Rain High up mountains Low Biotic diversity

Questions! What do the abiotic factors of a tropical rainforest tell you about the plants that live there? They need warm temperatures and lots of water How are tundra and a desert alike and different? Both have little rainfall, but a desert is very hot and a tundra is very cold. What abiotic factors affect the traits that desert animals have? The hot, dry conditions
