ECOLOGY The study of interactions of organisms and their environment
Levels of Organization Individual Organisms (Species) Populations Communities Ecosystems Biosphere
Organisms/Species A human (Homo sapien) Deer Piranaha Worm Bigfoot?
Populations Same species living in same area Species? -can breed and produce offspring that can have babies
Communities Coral Reef Cedar swamp Vernal pool
Ecosystems Tropical rainforest Desert Temperate deciduous forest (ours) Ponds Coral reef
Physical Conditions ABIOTIC - non-living Sunlight Water Temperature Soil Wind Disturbance BIOTIC - living things Bacteria Protists Fungus Plants Animals
PRODUCER - an organism that makes its own food (autotroph) - becomes food for other organisms.
CONSUMER - organism that obtains food by eating others (producers or other consumers)
DECOMPOSER - organism that breaks down wastes and dead organisms
HERBIVORE - consumer that eats only producers.
OMNIVORE - consumer that eats both producers and consumers (plants, fungi, and meat)
CARNIVORE - consumer that eats only other consumers (exclusively meat-eaters)
FOOD CHAIN - pathway of food transfer from one trophic level to another.
FOOD WEB -pattern of feeding in an ecosystem consisting of interconnected and branching food chains
Primary Succession The development of brand new land – (volcano created new land)
Secondary Succession A once established forest is destroyed and has to start growth over. For example a forest fire
Mutualism Both species benefit
Commensalism One species benefits the other gets nothing
Parasitism One species harms another Think parasite
Predation Predator Prey – One eats the other
Interactions of Living Things Guided Notes Food Chains, Food Webs, and the Transfer of Energy.

EcologyEcology: the study of interactions that take place between organisms and their environment Ecology.
Ecology By Ashley Olsen. What is ecology? Ecology is Ecology is the study of the relationship between the environment and living organism Their interactions.
Life Science Ecology & the Environment. Ecology Study of the interactions that take place among organisms and their environment.
Ecology. Ecology Ecology is the study of interactions between different kinds of living things and their environment. Ecology is the study of interactions.
Interactions within Communities Chapter 24, Section 3.
What is Ecology? Ecology Definition - the study of interactions among organisms and between organisms in their environment.
Ecology The study of interactions that take place between organisms and their environment.
How are species on our planet connected?. Layers of our Planet Geosphere: solid part of earth that consists of soil, rock and sediments. Geosphere: solid.
Food Chains and Food Webs Energy Flow in Nature. Energy Roles An organisms energy role in an ecosystem may be that of a producer, consumer, or decomposer.
Ecology. What is Ecology? Ecology is the study of interactions among organisms and between organisms and their environment. Ecology is the study of interactions.
An ecosystem is a complete community of biotic and its abiotic environment. An ecosystem can be as large as the Sahara Desert or as small as a puddle.
Chapter 2 Principles of Ecology You will learn: 1. What an ecologist does. 2. Some important aspects of an organisms environment. 3.Trace the flow of energy.

Ecology Jeopardy Jeopardy Quiz Review Game. Biotic or Abiotic? What am I?What goes around comes around Webs, chains, pyramids, & relationships Ecological.
Ecology Movement of energy. Know the 3 Es Ecology = the study of the relationship between organisms and their environment. Ecosystem = all the living.
Ch 36 Energy in Ecosystems Ch 36 Energy in Ecosystems 36.1 Food Chains & Food Webs.
Energy Transfer in Ecosystem Vocabulary Trophic = nutrition –Autotrophs –Heterotrophs.
I. Energy Flow A. Producers / Make their own food through photosynthesis / Examples: Plants, algae A. Producers / Make their own food through photosynthesis.
Ecology: the study of the interactions of living things with each other and their physical environment.
Ecology Review Questions Multiple Choice The natural world that surrounds an organism is called the organisms: a. energy b. environment c. lodgings d.
Ecology Note Card Challenge Who has many individuals of the same species living in the same area? I have ECOLOGY.
Ecology. Ecology is the study of the interactions of living organisms with one another and with their physical environment (soil, water, climate…) ECO.

Principles of Ecology Chapter 2.1 Biotic & Abiotic Factors Biotic = Living organisms Abiotic = Nonliving Soil,Air,Water Substrate.
THE SILENCE OF THE FROGS Chapter 1.1. Amphibians have been around for more than 400 million years. Frogs and their relatives have adapted to the ice.
