THE 3 DIFFERENT TYPES OF ECOSYSTEMS

Kawaii panda world

WHAT IS AN ECOSYSTEM?

An ecosystem is an interaction between members of theA biotic community And understands their interaction with the non-living environment. The environment determines which organizations can live where, and how many can live there. These organisms live in a specific type of environment called habitat.

For example, a worm lives in the soil. The worms have a very delicate and humid skin. They die if they are exposed for a long time to the sun and the wind over the ground. Soil is an example of land or terrestrial habitat.

Another example is that of frogs. Frogs spend much of their life in a pond. A pond is an example of aquatic habitat, specifically freshwater habitat.

Each Habitat Has its own set of environmental factors that make it different from other habitats. Some of these factors are moisture content, temperature, amount of sunlight, salt content, and soil type. These factors determine the plants and animals that can live in these environments.

In other words, living things are affected by the non-living or abiotic factors of the environment.

WHAT ARE THE CHARACTERISTICS OF AN ECOSYSTEM?

The different types of ecosystems on the earth's surface share particular characteristics such as energy flow through a tropical structure, continuous energy supply, energy pathways, and the interaction of the populations of organisms in an ecosystem.

Energy Arrives in the world living in the form of sunlight. Green plants trap this energy and store it as a chemical energy of food.

Food consists of nutrients or chemicals that serve as sources of energy and building materials to an organism. These substances are transmitted from one organism to another in a food chain.

In a food chain, the chemical energy of food is transferred through a series of organisms, which eat and are eaten repeatedly. A food chain is both a food route and an energy route.

As energy is transferred from one trophic level to another, less of the initial energy becomes available to higher order consumers. In this case, the energy transfer in the biosphere can be presented in the form of energy.

1) NATURAL ECOSYSTEM

A) DRILLS

The original forests Are also called primary forests. When the trees of the forest are felled and pushed back, the forest is called secondary forest or second-growth forest. The lowland primary forests include mangrove forests, the forests of Dipterocarpaceae, and the forests of Malvales.

In the uplands, they include pine forests and moss forests. There are also tropical rainforests that are characterized by high temperatures and significant rainfall throughout the year.

The type of Tropical rainforest The richest is the forest of Dipterocarpaceae. It has the largest number of plant and animal species. The thick canopy is the richest habitat for birds.

The thick layer of decaying leaves on the forest floor is the richest habitat for leeches, centipedes, centipedes, and land snails. The intact Dipterocarpaceae forest abounds in mammals, birds, reptiles and insects that live in trees, on the ground and in the earth.

B) GRASSLANDS

The term "Grassland" Refers to a land with a natural grassy cover, without trees or with very few widely dispersed trees. Most of the grassland in tropical countries is the result of forest destruction, and some are natural formations.

For example, the dominant vegetations in many of the grasslands of the Philippines are the cogons along the hills and talahib in the plains where there is more water. These grass species require abundant sunshine. Prairie animal species include snakes, lizards, rats, birds and insects.

C) COASTAL AREAS

The term "Coastal zone" Is a type of ecosystem designating a strip of land on the shore of the sea or a lake.

It includes both exposed and submerged parts of the earth. The coastal zone includes mangrove forests, beaches, tidal zones and coral reefs.

Coastal zone ecosystems vary greatly in terms of biotic and abiotic components, and mangrove forests and coral reefs are among the richest habitats.

For example, a mangrove forest includes many species of trees in which birds, lizards, snails, and insects live. In the water below, there is a wide variety of fish, crabs, shrimps and molluscs.

2) ARTIFICIAL ECOSYSTEMS

A man-made ecosystem Is a kind of ecosystem that is built and maintained by humans. Artificial ecosystems are unique in that people deliberately play a major role in the functioning of the ecosystem. Examples of artificial ecosystems include rice paddies, fish ponds, and urban ecosystems.

Rice is a type of agricultural ecosystem. Agricultural ecosystems cover crops planted with crops such as corn, sugarcane, tobacco, cotton, coconut and abaca. Southeast Asian countries such as the Philippines, Thailand and Indonesia are examples of countries with many types of agricultural ecosystems.

In some areas, freshwater lakes are considered an artificial ecosystem because they are used as fish ponds by constructing fish pens near the shore. The Laguna and Sampaloc lakes in the Laguna province of the Philippines are two examples.

Urban land is also considered an artificial ecosystem because it is designed for people's homes as well as for their support activities. Townsites, parks and cemeteries are examples of urban land.

3) SPECIAL MICRO-ECOSYSTEM

If you are looking closely Different habitats on land and in water, you will see that within each one there are smaller habitat units where the interaction is less important.

Such small-scale interactions characterize a microecosystem. Some examples of microecosystems are the fusion of hay in the laboratory, a log that has fallen on the forest floor, the decomposing fruit on the market stalls and the soil where different types of organisms live.
