ECOLOGY The Study of the Interaction of organisms with their environment
The Environment Biotic Factors all of the living things in the environment Abiotic Factors all of the nonliving things in the environment
Community All of the living things in an area that DEPEND on each other
Relationships in a Community -1 Symbiosis = “Living Together” –Close relationship between two or more species –Examples Mutualism Commensalism Parasitism
Mutualism Both species benefit from the relationship WIN – WIN EX: acacia tree and ants.
Commensalism One species benefits from the relationship and the other is unaffected. WIN – “I don’t care” EX: Orchid
Parasitism One species benefits (parasite) and the other is harmed (host) WIN – LOSE EX: Tick Parasite does not want to kill the host. Why?
Relationships in a Community - 2 Predation - The feeding of one organisms on another –Predator hunts/eats –Prey gets eaten
Habitat The Place where an organism lives
Niche The JOB of an organism in a community
Niches in a Community PRODUCER CONSUMER DECOMPOSER
Producer (Autotroph) Plants make food in a community Photosynthesis –using sunlight to make food
Consumer (Heterotroph) Can’t make their own food Primary Consumer Eats plants Secondary Consumer Eats other animals
Decomposers Are consumers Get food by breaking down dead matter Recycle nutrients Examples –Fungi (molds, mushrooms) –Bacteria
Energy The ability to do work Flows through an ecosystem What is the primary source of energy in an ecosystem? The Sun
Food Chain Pathway of energy through an ecosystem Sun Grass Producer Grasshopper Primary Consumer Bird Secondary Consumer
Food Web Food chains connected in a community All of the possible feeding relationships
Energy Pyramid PRODUCER PRIMARY CONSUMER SECONDARY CONSUMER TERTIARY CONSUMER
Energy Pyramid Shows energy loss in a food chain –90% lost as heat # of organisms at each level decreases –Less energy available Because of energy loss, maximum of 5 levels.
Interactions of Living Things Guided Notes
Interdependence and interactions in an ecosystem
Studying the Web of Life
12A Interpret relationships (predation, parasitism, commensalism, mutualism, competition) among organisms.
ecology ecosystem abiotic
Food Chains, Food Webs, and the Transfer of Energy
Interactions of Living Things
The interaction of organisms with the environment.
ECOLOGY AND ECOSYSTEMS Ecosystem Includes abiotic and biotic factors Biomes are examples Community Includes all the LIVING things Population All of one.
Eco-friendly A special relationship Web Browser What’s.
Movement of Energy Through an Ecosystem: Producers and Consumers PRODUCERS (autotrophs) –plants, bacteria and algae are the first to capture the energy.
Everything is Connected
Intro to BIOLOGY Bio= Life Logy= Study of. What are the characteristics of living things?
Chapter 16 Notes Interactions of Living Things
ECOSYSTEMS. ECOSYSTEMS & ECOLOGY Ecology is the study of the interactions of living organisms with one another and their physical environment.
EQ: How do Energy and Matter Move In an Ecosystem?
Ecology: The study of Interactions among Organisms and its environment including: Abiotic factors are nonliving factors such as temp. soil, air, rocks.
What is Ecology? The study of the interactions between organisms and their environment Interactions between organisms is not simply who eats who but.
