http://ecology.com/tv/vidpages/ biodaversity.php Ecology: an introduction What is Ecology?

The study of living things and how they interact with their environment. Ecosystem All the organisms living in an

area and how they interact with both living and non-living things. Two Factors Organisms Interact With: Biotic living

Abiotic nonliving Identifying Biotic and Abiotic Factors of Your School Ecosystem

Water Air Soil

Temperature Sunlight Warm-up Take out a sheet of paper and answer the following questions:

1. 2. 3. 4. Todays warm-up will be collected! Draw a diagram of an ecosystem where you live (the desert).

Label all of the abiotic and biotic factors. Give two examples of how plants and animals affect their environment. Describe how temperature, light, and soil (all abiotic factors) affect an ecosystem. Predict what will happen: Think of a forest ecosystem. Now imagine that a large volcanic eruption throws large amounts of

dust and ash into their air; blocking out the sun. How might the forest ecosystem be affected if the sunlight is blocked for a day? Then predict if the sunlight were blocked for a year. What would happen to the plants and animals of that ecosystem? Warm-up Get your ISN and turn to the page

Draw an ecosystem on a half sheet of paper: Label three biotic factors Label three abiotic factors This will be graded!

Parts of an Ecosystem (From Smallest Level To Largest Level) Organism- A single living thing Population

All the organisms in an ecosystem that belong to the same species (biotic) Population of Dragons (All the same species)

Community All the populations in an ecosystem (biotic) Community

Habitat The place in which an organism lives. Provides Basic Needs Food, Shelter, Temperature,

for animals survival. Energy Roles Within An EcosystemAn organisms energy role is determined by how it obtains

energy & how it interacts with other living things. The three energy roles are producer, consumer, & decomposer. PRODUCERS

A producer is an organism that can make its own food. These organisms are called autotrophs. CONSUMERS

A consumer is an organism that obtains energy by feeding on other organisms. These organisms are called: Heterotrophs. Consumers are classified by what

they eat.. Carnivores: Only eat other animals Herbivores: Plant eaters Omnivores: Eat both animals and plants Scavengers: Eat the remains of dead animals. (example: vultures)

DECOMPOSERS Decomposers are organisms that break down wastes & dead organisms

Two major groups are bacteria & fungi Identify the following pictures as. Producers Consumers Or

Decomposers Now Identify the pictures as.. Carnivores (only eat meat) Herbivores (only eat plants) Omnivores (eat both plants and

animals) or. Scavengers (eat the remains of dead animals!) Warm-up Complete the warm-upon your desk We will grade this in class

Food Chains/Food Webs A food chain shows what is eaten. The lettuce is eaten by the

rabbit. Food chains always start with a plant. The lettuce is eaten by the slug, the slug is eaten by

the bird. Food Chains A reminder A food chain shows which animals eat other animals or plants.

Plants dont eat things. A food chain starts with what gets eaten and the arrows point towards what does the eating. Food chains only go in one direction. Where do the arrows point?

The top of the food chain. Some animals are said to be at the top of the food chain. This is because they are not hunted by other animals. No other animal hunts the lion. The lion is at the top of the food chain.

Can you think why? Food Webs In the wild, animals may eat more than one thing, so they belong to

more than one food chain. To get the food they need, small herbivores may eat lots of different plants, and carnivores may eat many different animals. Food Webs

We can show this by using a food web, which is just a more complicated version of a food chain. owl fox rabbits

mice grass seeds

berries Breaking the Chain Organisms living in a habitat depend on each other.

If one part of a food chain dies out or is greatly reduced, the consumers have to find alternative food, move away, or starve. This then affects more consumers in the same way.

Your Assignment Using Microsoft Word: you and your partner will create two food chainsYou should have a least 5 steps in your chain. Then take your two food chains and connect them into a food web

Put your name on your assignment, print a copy of your food chains and web staple it together and turn it into the bin. Carrying Capacity The maximum number of individuals of

any species that can be supported by a particular ecosystem on a long-term basis
