What Is A Biome?
Uncategorized
Biome is a group of ecosystems that have a similar climate and have similar plant and animal species.
The word ecosystem is short for ecological systems. An ecosystem is a place where living things such as goanna's and non living things such as rocks live in a shared environment. An ecosystem can be small as a pond or as large as an ocean. Scientists talk about general ecosystem types. They call them biomes. A biome is a group of ecosystems that have a similar climate and have a similar plant and animal species. There are a number of different types of biomes, including fresh water. Marine. Desert, forest, grassland, and tundra. Let's start with fresh water. Fresh water is defined as having a low salt level. Usually less than 1%. Places and animals that live in fresh water ecosystems would die if they were placed in water with high levels of salt.
There are different types of fresh water areas, including ponds, lakes, rivers, streams, and wetlands. Marine regions cover about 75% of the earth's surface. Oceans and coral reefs are examples of marine bayerns. Marine regions differ from freshwater regions as they have high levels of salt in the water. It's home to millions of species of animals. A desert is an area that receives less than 50 centimeters of rain each year. They're extremely dry places and cover about one 5th of the earth's surface. The Simpson desert occupies approximately 176,000 km² of central Australia. Forests cover about one third of the earth's land area. And a made up of many trees. Trees breathe slightly differently from humans and other animals. Trees breathe in carbon dioxide and exhale, oxygen. Humans need oxygen to breathe. That's why it's important that we protect our forests.
Grassland ecosystems are land areas that are covered by grasses. Grasslands can be split into two groups. Savannah and temperate. Savannah grasslands are always found in warm, hot, or tropical climates. The savannas of northern Australia, including the kimberley region, are typical of this. Temperate grasslands exist in varied climates, with coal winters. And hot summers. Australia's kangaroo island and cradle mountain in Tasmania are examples of these biomes. The tundra biome is the coldest of all the biomes. Like Churchill in Manitoba, Canada. Tundra ecosystems have very low temperatures. A cabin in ice and don't add much rain.
