Ecosystems and Communities Chapter 4 -2

What Shapes an Ecosystem? l What kinds of things do we find in an ecosystem?

Ecosystems l Ecosystems are made up of two types of things: l Biotic Factors l l Living things Abiotic Factors l Non-Living Things

Abiotic Factors Biotic Factors ECOSYSTEM With a community

l l In this scene… What is abiotic? What is biotic? How do they relate to each other?

Ecosystems l l Organisms have specific spaces within a habitat they occupy Habitat l The biotic and abiotic factors that are required for an organism to survive l l An organisms address Niche l All physical and biological conditions in which an organism lives and how it uses those conditions l An organisms job

What is a niche? Cape May Warbler Feeds at the tips of branches near the top of the tree Bay-Breasted Warbler Feeds in the middle part of the tree Spruce tree l Yellow-Rumped Warbler Feeds in the lower part of the tree and at the bases of the middle branches A niche is the physical and biological conditions in which an organism lives and the way the organism uses those conditions

Community interactions l l How communities in ecosystems interact with each other? Community interactions (definition) l l l Competition (organism use the same resource) Predation (one feeds off another) Symbiosis (two live closely; need the other) l l l Mutualism (both benefit) Commensalism (only one benefits) Parasitism (one benefits, other is harmed)

Question l l l When we look at Lawndale, was there a school here a year ago? 5 years ago? 1000 years ago? What has happened to the environment over time? l change

Ecological Succession

Change and time in an ecosystem l Ecosystems changing in response to natural and human disturbances l l l Ecological succession Old inhabitants gradually die or move; new organism move in Examples or causes of ecological succession? l l l Dinosaurs and meteors Grand canyon People and global warming

Review l l What is the difference between Climate and Weather? What is the difference between something that is Biotic and something that is Abiotic? A _____ is like an organisms address in an ecosystem, and it’s _____ is like its job Give an example of Predation
