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
Ecology Terms Review. A carnivore that feeds on the bodies of dead organisms.
Food Webs Within Ecosystems Marine, Freshwater, and Terrestrial FOOD WEBS.
Ecosystem Notes Organism: a living thing Individual: one single organism Population: all the individuals of one kind (one species) in a specified area.
Relationships in an Ecosystem. Instructions: View this powerpoint on concepts and terms that will be useful to you in understanding relationships within.
Ecology. Ecology - the study of interactions among organisms and between the organisms and their environment. These interactions occur in the biosphere.

ECOSYSTEMS. ECOSYSTEMS & ECOLOGY Ecology is the study of the interactions of living organisms with one another and their physical environment.
PRINCIPALS OF ECOLOGY CHAPTER 3 BEGININIGS OF ECOLOGY ECOLOGY- SCIENTIFIC STUDY OF INTERACTIONS BETWEEN ORGANISMS AND THEIR ENVIRONMENTS ECOLOGY- SCIENTIFIC.
Ecology. WHAT IS ECOLOGY? Ecology- the scientific study of interactions between organisms and their environments, focusing on energy transfer Ecology.
Ecological Relationships. Biosphere The biosphere is the portion of the earth in which living things and non-living things exist. The ecosystem is.
Ecology. Everything is Connected __________- the study of the interactions between organisms and their environment Ecology.
Ecology Study of interactions between organisms and their environments.
Introduction to Ecology (Ch. 3) Why should I learn about Ecology? 1.
Ecosystems Food Chains/Webs, Energy Pyramids, Symbiotic Relationships Predatory-Prey Interaction, & Competitions James, 2009.
Competition – two species share a requirement for a limited resource reduces fitness of one or both species.
Ecology. Define Ecology study of the interactions that take place among organisms and their environment.

INTERACTION OF LIVING THINGS AND CYCLES IN NATURE. Chapter 2 and 3 review.
ECOLOGY!. What is Ecology? - study of the interactions among organisms and between organisms and their environment. Some Vocabulary Review!
Principles of Ecology Unit 2 Chapter 2. What is ecology? Ecology: study of interactions that take place between organisms and their environment.
Movement of Energy Through an Ecosystem: Producers and Consumers PRODUCERS (autotrophs) –plants, bacteria and algae are the first to capture the energy.
Chapter 18 Interactions of Living Things The study of the interactions between organisms and their environment Click for Term.
Levels of Organization. What is Ecology? The study of interactions among organisms and between organisms and their environment (surroundings)
Ecology The study of the interaction of living things with their environment.
CHAPTER 1E Interactions of Living Things. Everything is Connected….. ALL Living things are connected somehow Ecology – the study of how they are connected.
What is Ecology? – study of interactions between creatures & their environment, because… Everything is connected to everything else.
ECOLOGY A FEW TERMS. BIOTIC FACTORS The things that are living, or that came from living things EXAMPLES: Plants Animals Bacteria Fungus (mushrooms, yeasts)
Vocabulary Review Ecology. Portion of earth that supports life. Biosphere.
Ecology Introductory Terms. Ecosystem Biotic Factors Abiotic Factors Interacting Energy.
Ecology & Ecosystems Ecology is the study of the interactions between organisms (biotic factors) and their environment (abiotic factors) Abiotic Factors:
Chapters 3-5 Biology – Miller • Levine
Ecology and Energy Flow. Vocabulary Ecology: the study of the interactions among organisms and their environments between biotic (living) and abiotic.
Interactions of Living Things
Part 1 Ecology:the study of the interactions of living organisms with each other and their environment.
A grouping of the same species in a certain area.
ORGANIZATION IN THE BIOSPHERE. LIVING THINGS, AS WE KNOW THEM, ARE CONFINED TO A SPECIFIC AREA OF EARTH THAT WE CALL… THE BIOSPHERE !!
Ecology. What is Ecology? Ecology is the study of interactions among organisms (biotic factors) and between organisms and their environment (abiotic factors).
Interdependence and interactions in an ecosystem
Regents Review 4 Ecology: The Biosphere. Ecology Basic Terms Define the term biotic Biotic – living part of the ecosystem Plants animals Define the term.
Topic: Ecology Learning Goal: I can describe relationships (producer/consumer, predator/prey, and parasite/host) as they occur in food webs. Essential.
Intro to Ecology Study of how organisms INTERACT with each other and their environment.
Studying the Web of Life
Interactions of Living Things May Living or Not Living? Biotic – any living thing in an ecosystem –Examples: (list our class examples) Abiotic –
An ecosystem is made up of a community of organisms and the non-living environment. The living components of the ecosystem are called biotic factors, which.
