ECOSYSTEM

An Ecosystem is a community of organisms interacting with each other and with their environment such that energy is exchanged and system-level processes, such as the cycling of elements, emerge. The ecosystem is a core concept in Biology (natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy) and Ecology (relationships between organisms and their environments), serving as the level of biological organization in which organisms interact simultaneously with each other and with their environment. As such, ecosystems are a level above that of the ecological community but are at a level below, or equal to, biomes and the biosphere. Essentially, biomes are regional ecosystems, and the biosphere is the largest of all possible ecosystems in Tropical Rain Forest. Ecosystems include living organisms, the dead organic matter produced by them, the abiotic environment within which the organisms live and exchange elements, and the interactions between these components. Ecosystems embody the concept that living organisms continually interact with each other and with the environment to produce systems with emergent properties, such that "Everything is Connected".

The SUNLIGHT is the main source of energy in the Food Chain. Sunlight allows the plants to convert energy by photosynthesis. This provides food for birds, fish and other types of animals. These animals are called Herbivores. other animals eats animals that eats plants. These animals are Carnivores. And the other animals that eats meat and plants. These are called Omnivores. This process is called FOOD CHAIN.

Examples of Food Chain

1. Plants > grasshopper (first) > rat (second) > snake (third) > hawk (fourth) > bacteria

2. Plants > insect (first) > small fish (second) > big fish (third) > Eagle (fourth) > bacteria

3. Algae > small fish (first) > big fish (second) > sea lion (third) > Shark (fourth) > bacteria

" Food Chain always starts with the producer next the 1st consumer up to 4th consumer and it ends up with decomposer or bacteria "

We can help our ECOSYSTEM by:

> Plant only indigenous plants in your landscape and garden. Every region on the planet has plants that have evolved and adapted to the conditions within that region. By refraining from adding non-native plants to your immediate environment, you encourage the natural balance of your region.

> Avoid throwing garbage at the streets, rivers, bay and forest.

>Avoid the use of synthetic pesticides, herbicides and fertilizers in your garden and lawn. These products kill indiscriminately and might seep into the ground water. Both of these consequences result in upsetting the natural balance of the local ecosystem.
