Everything is connected!

Studying the Web of Life.

abiotic factors
Abiotic Factors
  • Any nonliving thing is an abiotic factor. Write at least 4 examples1. oxygen2. carbon dioxide3. sunlight, temperature 4. wind5. water

6. sand

7. rocks

8. soil

biotic factors
Biotic Factors

A biotic factor is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes. Each biotic factor needs energy to do work and food for proper growth. Biotic factors include human influence.

Biotic components usually include:

Producers

Consumers

Decomposers

how do abiotic and biotic factors depend upon each other
How do abiotic and biotic factors depend upon each other?
  • Abiotic and biotic components influence each other. For instance, temperature (abiotic factor) can make plants (biotic factor) reproduce more or reproduce less. Also water, an abiotic factor, has an effect on how animals, a biotic factor, survive in certain areas of the world. In Africa, for instance, the migratory patterns of most herbivores are based where water is the most plentiful. When the dry season comes, the animals must move to where the food and water are most abundant.
the five levels of environmental organization
The five levels of Environmental Organization.

1.Organism

2.Population

3.Community

4.Ecosystem

5.Biosphere

first level organism
First level - Organism
  • In individual is a single organism.
second level population
Second level – population

A population is a group of individuals of the same species in the same area. For example, all the alligators in the same river make a population. The whole population uses the same area for food and shelter.

third level community
Third level - community

A community is made up of all the different populations that live and interact in the same area. The different populations in a community depend on each other. For

example, alligators eat other animals, including fish .Alligators create water-filled holes where fish and other organisms in the river can live during dry seasons.

.

fourth level ecosystem
Fourth level-ecosystem
  • An ecosystem is made up of a community and its abiotic environment. The abiotic elements provide resources for all the organisms and energy for some.

A river, for example, can provide water for river plants and many animals, and shelter for water insects. It can provide nutrients for plants, as well as food for fish and alligators.

fifth level biosphere
Fifth level - Biosphere
  • The biosphere is the part of Earth where life exists. The biosphere is the largest environmental level. It reaches from the bottom of the ocean and the Earth’s crust to high in the sky.
can you identify the following
Can you identify the following:

Organism,

populations,

community.
