IV. LEARNING MATERIAL

Concept Map:

Ecosystem

1. The Energy Flow in an EcosystemIf you observe the ecosystem being discussed before, you will then understand how the

relationship among organisms. Food is necessary for every organism including producers,

consumers, or even decomposers. How do they interact ?

Do you remember the process of photosynthesis? Plants trap the energy of sunlight and

use it to do chemical reaction. It changes water and CO2 into starch and oxygen. Starch is food

(chemical energy) stored by plants. When animals eat the plants, the energy is transferred to

animals. This transfer of energy from one organism to another is called energy flow. The flow of

energy can be shown by food chain and food web.

Food Chains

The plants energy is transferred to animals when grasshopperss, as consumers, eat rice. Then,

they are eaten by frogs. So, the energy is transferred from one animal to another gradually. The

energy is also transferred when decomposers decompose dead organisms. The process of eating

and being eaten is called a food chain. A food chain is an example of how food energy is

transferred from one organism to another in an ecosystem.

Shows components of a simple food chain. Plants produce food for themselves. They

store the food in their roots, stalks, and leaves. Animals eat plants and then they are eaten by

other animals. This is how the solar energy is spread all over the ecosystem.

Food Webs

In an ecosystem, the organism may get food from more

than one kinds of organism. An eagle may eat a lizard, a

small bird, or a rabbit. A small bird eats a carterpillar, a

snail, or fruit. Those make up many interconnected food

chains.A network of interconnected food chains is called

of a food web.

Energy piramyd

Each activity requires energy. From which living things get energy? Energy source for

organisms is chemical energy contained in food. Living beings are not capable of creating

energy, but rather just move and use to move. Energy transfer takes place from the sun to green

plants through photosynthesis. Here, light energy is converted into chemical energy. When green

plants eaten by herbivores, chemical energy stored in plants moved into the body

herbivores and some energy is lost in the form of heat. Similarly, when carnivores eat herbivores.

Therefore, the flow of energy in the reduced amount of the food chain. Movement of energy in

ecosystems is only one path, a flow of energy.

Tropical and level of the Food Pyramid

In the food chain we have seen that the trophic level consists of producers, consumers

levels I, II consumer level, and so on. Producers who are autotrophs always occupy the major

tropic levels, herbivores occupy the second trophic level, carnivores occupy the third trophic

level, and so on. Any transfer of energy from one trophic level to the next trophic level will be

the release of some form of thermal energy so that the amount of energy in the food chain to

higher trophic levels, the numbers are fewer and fewer. Pyramid is formed ecology / food

pyramid.
