Introduction to Ecology

By:

Brianna Shields

October 29, 2004


DO NOW- have current event out on your desk

  • 1. What is the primary source of energy on the planet?

  • 2. What is a “baby” frog called?

  • 3. What process do autotrophs carry out in order to make glucose and oxygen?


GOAL

  • To define ecological vocabulary words

  • To distinguish between several biomes

  • To differentiate between the ecological relationships found in nature


Ecology Video Questions

  • 1. What is a community?

  • 2. What is a population?

  • 3. What is a habitat?

  • 4. What is a niche?


Ecology

Study of the relationships between living things and the environment

Ecological Relationships


Biosphere

Thin zone of life above and below earth’s surface

Ecological Relationships


Biome

Portion of biosphere with specific temperature and amount of rainfall

Tundra

Rainforest

Ecological Relationships


Ecosystem

Living and nonliving things in an environment

Ex:

Ocean

Forest

River

Lake

Ecological Relationships


Community

All the living organisms that share the same environment

Ex:

A community of trees, flowers and reptiles

Ecological Relationships


Population

One type of species living in an area

Ex:

Population of Zebras

Ecological Relationships


Habitat

An organism’s “special place” or home in an ecosystem

Ex:

Swallow (bird) habitat = tree

Ecological Relationships


Niche

An organism’s specialized job within an ecosystem

Ex:

Tiger= carnivore- eats other animals (meat)

Ecological Relationships


Abiotic Factors

Non living things in the environment

Ecological Relationships


Biotic Factors

Living things in the environment

Ecological Relationships


Assessment: Ecological Relationships

  • What is this organism’s niche?


Assessment: Ecological Relationships

  • What type of ecosystem is this?


Assessment: Ecological Relationships

  • What makes up this community?


Assessment: Ecological Relationships

  • What types of population is present in this picture?


Assessment: Ecological Relationships

  • Describe this biome


Assessment: Ecological Relationships

  • What items make up this ecosystem? List atleast 5 biotic and/ or abiotic factors


Assessment: Ecological Relationships

  • What would be this organism’s habitat?


Assessment: Ecological Relationships

  • List 3 biotic factors from this picture:


Assessment: Ecological Relationships

  • List 3 abiotic factors from this picture:


Tundra

1. Cold, snow, ice

2. Short summers

3. Poor soil, permafrost

4. Flat ground

5. Very few plants and animals

Ex: reindeer, fox

Biomes

Deciduous Forest

1. Trees that shed leaves

2. Moderate temperatures

3. Good water supply

4. Many animals

Biomes

Coniferous Forest

1. Pine trees

2. Cold temperatures in winter

3. Thick forests, little sun

4. Not many small plants

5. Animals: squirrel, deer, mountain lions, fox, birds, insects

Biomes


Coniferous Forest Picture


Grassland/ Savannah

1. Lots of grass

2. Moderate temperatures

3. Fairly dry, little rain

4. Not many trees

5. Grazing and burrowing animals

6. Good farmland for wheat and corn
