Science for Kids: World Biomes and Ecosystems
Temperature, soil, and the amount of light and water help determine what For example, an aquatic biome can contain ecosystems such as. An ecosystem is a community of living and non-living things that work ecosystem that helps keep the system healthy. the relationship between the biome. Ecosystems are closely related to biomes because there are many ecosystems within a biome. from Middle School Life Science: Homework Help Resource.
Ecologists use other specific names that describe what type of food a consumer eats: Omnivores eat both animals and plants. Once again, knowing the Latin root helps a lot: For example, an insectivore is a carnivore that eats insects, and a frugivore is an herbivore that eats fruit.
This may seem like a lot of terminology, but it helps scientists communicate and immediately understand a lot about a particular type of organism by using the precise terms. Not all organisms need to eat others for food and energy. Some organisms have the amazing ability to make produce their own energy-rich food molecules from sunlight and simple chemicals. Organisms that make their own food by using sunlight or chemical energy to convert simple inorganic molecules into complex, energy-rich organic molecules like glucose are called producers or autotrophs.
Some producers are chemosynthesizers using chemicals to make food rather than photosynthesizers; instead of using sunlight as the source of energy to make energy-rich molecules, these bacteria and their relatives use simple chemicals as their source of energy. Chemosynthesizers live in places with no sunlight, such as along oceanic vents at great depths on the ocean floor.

No matter how long you or a giraffe stands out in the sun, you will never be able to make food by just soaking up the sunshine; you will never be able to photosynthesize.
Producers use the food that they make and the chemical energy it contains to meet their own needs for building-block molecules and energy so that they can do things such as grow, move, and reproduce. All other life depends on the energy-rich food molecules made by producers — either directly by eating producers, or indirectly by eating organisms that have eaten producers.
Not surprisingly, ecologists also have terms that describe where in the food chain a particular consumer operates. A primary consumer eats producers e. And it can go even further: A single individual animal can act as a different type of consumer depending on what it is eating.
When a bear eats berries, for example, it is being a primary consumer, but when it eats a fish, it might be a secondary or a tertiary consumer, depending on what the fish ate! All organisms play a part in the web of life and every living thing will die at some point.
This is where scavengers, detritivores which eat detritus or parts of dead thingsand decomposers come in. They all play a critical role that often goes unnoticed when observing the workings of an ecosystem.
They break down carcasses, body parts and waste products, returning to the ecosystem the nutrients and minerals stored in them. This interaction is critical for our health and health of the entire planet; without them we would be literally buried in dead stuff.
Crabs, insects, fungi and bacteria are examples of these important clean-up specialists. Another category of interactions between organisms has to do with close, usually long-term interaction between different types of organisms.
These interactions are called symbiosis.
What is the relationship between the biosphere, a biome, and an ecosystem?
The impacts of symbiosis can be positive, negative, or neutral for the individuals involved. Organisms often provide resources or services to each other; the interaction is mutually beneficial. For example, ants living in a tree may protect the tree from an organism that would like to make the tree its next meal, and at the same time the tree provides a safe home for the ants. Symbiotic relationships are not always positive for both participants.
Sometimes there are definite losers. The predator benefits and the prey is harmed lethally, but it is a short-term interaction. In parasitism, the parasite does not usually kill its host, but just feeds on it for a long time while it is living.
It is important to preserve all types of biomes as each houses many unique forms of life.
However, the continued heavy exploitation of certain biomes, such as the forest and aquatic, may have more severe implications. Forests are important as they are home to the most diverse biotic communties in the world.
Hidden within these biomes are potential medicines and many thousands of unseen and undiscovered species. Also, forests have a global climate-buffering capacity, so their destruction may cause large-scale changes in global climate. Logging has depleted many old-growth temperate forests. The increased demand for homes, paper, and other wood products have not allowed for much conservation.
More recently, people have begun to realize that logging has cleared much of these forests. Wiser use of the forests and efforts to replant trees have helped to slow down the depletion of these communities. Tropical forests have fallen victim to timber exploitation, slash and burn farming, and clearfelling for industrial use or cattle ranching, particularly in Latin America. Our increasing demand for meat products has spurred these events. For years, this destruction was occuring at a rapid rate.
Public attention to this exploitation have helped to alleviate the problem somewhat, though many challenges are still to be faced. Aquatic biomes are probably the most important of all the biomes.
Their medium, water, is a major natural resource.
