What are three different types of ecosystems?

Answer 1

There are three main types of ecosystems on Earth. There are freshwater, oceanic, and terrestrial ecosystems.

The freshwater ecosystems take up only a small percentage of Earth's area, but can be seen in many places. Most rivers, lakes, reservoirs, and aquifers around the world are freshwater. They are home to many different species of animals including fish and amphibians. Several species of plants also grow by sources of freshwater, so this ecosystem provides much sustenance and shelter to all living things.

The oceanic ecosystems take up most of the Earth's surface and can be divided up into smaller ecosystems based on the depths of the water. Much of the Earth's photosynthetic plants live in the ocean and most of the known species of water-dwelling animals also live in the ocean.

There are seven terrestrial ecosystems and they give life to all the animals on land. The ecosystems are tropical rain forests, savannas, deserts, temperate grasslands, deciduous forests, coniferous forests, and tundras (this can be grouped into four groups which would be forests, grasslands, deserts, and arctic/alpine). Each ecosystem contains a unique set of living species in unique living conditions.

Answer 2

It depends on the ecosystem. Some have three and some have five. They all begin with a base called the producers which make their own energy using sunlight and are therefore green. Next come those that will eat plants (herbivores) and thirdly those that will eat the plant eaters (carnivores and omnivores).
If conditions are very dry and not suitable for much plant growth, this ecosystem will support only three. A desert is a good example. Most other places have four levels. Only two will support five: the temperate or tropical rain forests.

Answer 3

Three different types of ecosystems are forests, grasslands, and coral reefs. Each ecosystem has unique characteristics and supports different types of plants and animals. Forests are characterized by a dense tree cover, grasslands by vast stretches of grasses, and coral reefs by diverse marine life supported by coral structures.
