Ecology: Ecology: an introduction
The study of the interactions that take place among organisms and their environment
Biosphere The part of Earth that supports life Top portion of Earth's crust (lithosphere) All the waters that cover Earth's surface (hydrosphere) Atmosphere that surrounds Earth
Ecosystem All the organisms living in an area and the nonliving features of their environment Biotic – living Abiotic – nonliving
Biotic Biotic – living Plants Animals Single celled organisms Fungi
Abiotic Abiotic – nonliving Water Air Soil Temperature Sunlight
Parts of an Ecosystem
Population All the organisms in an ecosystem that belong to the same species (biotic)
Community All the populations in an ecosystem (biotic)
Habitat The place in which an organism lives provides the kinds of food and shelter, the temperature, and the amount of moisture the organism needs to survive
Niche The specific role that an organism plays in its ecosystem
Competition Food Space
Competition Competition caused by population growth affects many organisms, including humans Limits population size
Limiting Factor Anything that restricts the number of individuals in a population. Includes living / biotic and nonliving / abiotic features of the ecosystem
Carrying Capacity The maximum number of individuals of any species that can be supported by a particular ecosystem on a long-term basis
Energy Transfer Food Chains Food Webs Energy Pyramids
Today I will study the components of an ecosystem because I need to understand how living things depend on one another.
Ecology & the Environment
What is Ecology?.
Ecological Principles: A Brief Overview
Ecosystems are made up of both living and nonliving things
Ecology. The study of the interactions that take place among organisms and their environment.
Introduction to Ecology. Ecology The study of the interactions that take place among organisms and their environment.
Environmental glossary. Abiotic Non-living things in the environment: example - soil, air, water, temperature (NOT dead things - they would be biotic.
The study of the interactions among organisms and their environment. Ecologists are scientists who study these relationships. Two groups of environmental.
ECOLOGY. Ecology is: The study of the relationship between living organisms and their environment.
POPULATIONS & COMMUNITIES REVIEW. The nonliving things within the environment. ABIOTIC FACTORS.

ECOLOGY. What is Ecology? Ecology is the scientific study of the relationship between organisms and their environment Ecologists study these relationships.
Ecology. WHAT IS ECOLOGY? Ecology- the scientific study of interactions between organisms and their environments, focusing on energy transfer Ecology.
Notes: Biotic & Abiotic Factors. A. Ecology The study of interactions between organisms and their environment.
SPECIES A group of organisms that look like each other and can breed among themselves.
Ecology: Interactions of Life Biosphere- part of Earth that supports life; includes the top portion of Earth’s crust, all the waters that cover.
Ecology Chapter 2 Section 1 pp What is Ecology Ecology is the study of the interactions between organisms (living things) and the environment.
In your science folder create a page called ecology notes. Answer the questions on this slide show on that page. Do it by yourself first, when your group.
