What is Ecology??• The study of interactions that take place between organisms and their environment.
• It explains how living organisms affect each other and the world they live in.

Habitat & Niche• Habitat is the place a plant or animal lives
• Niche is an organism’s total way of life

The Nonliving Environment
• Abiotic factors- the nonliving parts of an organism’s environment.
• Examples include air currents, temperature, moisture, light, and soil.
• Abiotic factors affect an organism’s life.
![Page 5: Ecology introduction Me 23 slides What is Ecology?](https://reader036.vdocument.in/reader036/viewer/2022081511/56815ed4550346895dcd69a1/html5/thumbnails/5.jpg)

The Living Environment• Biotic factors- all the living organisms that inhabit an environment.
• All organisms depend on others directly or indirectly for food, shelter, reproduction, or protection.

Read; don’t copy.
The Biosphere• Life is found in air, on
land, and in fresh and salt water.
• The BIOSPHERE is the portion of Earth that supports living things.

Energy Flow• Energy in an ecosystem
originally comes from the sun• Energy flows through
Ecosystems from producers to consumers–Producers (make food)–Consumers (use food by eating producers or other consumers)
![Page 27: Ecology introduction Me 23 slides What is Ecology?](https://reader036.vdocument.in/reader036/viewer/2022081511/56815ed4550346895dcd69a1/html5/thumbnails/27.jpg)
27
Producers• Sunlight is the main source of energy for most life on earth.
• Producers contain chlorophyll & can use energy directly from the sun
![Page 28: Ecology introduction Me 23 slides What is Ecology?](https://reader036.vdocument.in/reader036/viewer/2022081511/56815ed4550346895dcd69a1/html5/thumbnails/28.jpg)
28
ConsumersHeterotrophs (e.g. animals) eat other
organisms to obtain energy.
• Herbivores–Eat Only Plants
• Carnivores–Eat Only Other Animals
![Page 29: Ecology introduction Me 23 slides What is Ecology?](https://reader036.vdocument.in/reader036/viewer/2022081511/56815ed4550346895dcd69a1/html5/thumbnails/29.jpg)
29
Consumers (cont’d.)• Omnivores (like humans)
–Eat Plants & Animals• Scavengers
– (like buzzards) Feed On Dead Plant & Animal Remains
• Decomposers–Fungi & Bacteria

from producers to various levels of consumers

Feeding Relationships (cont’d.)• Food Chain
–Simple Energy path through an ecosystem
• Food Web–More realistic path through an ecosystem made of many food chains

Trophic LevelsEach Level In A Food Chain or
Food Web is a Trophic Level.• Producers
–Always The First Trophic Level
–How Energy Enters The System
• Herbivores–Second Trophic Level

Trophic Levels• Carnivores/Omnivores
–Make Up The Remaining Trophic Levels
Each level depends on the one below it for
energy.
