What is the significance of producers to ecosystems

Countries of the Amazon rain forest, such as Brazil, Venezuela, and Ecuador, are underdeveloped. Cutting down trees to make room for crop s such as soy and corn benefits many poor farmers. These resource s give them a reliable source of income and food. Children may be able to attend school, and families are able to afford better health care.

However, the destruction of rain forest ecosystems has its costs. Many modern medicine s have been developed from rain forest plants. Curare , a muscle relaxant, and quinine , used to treat malaria , are just two of these medicines.

Many scientists worry that destroying the rain forest ecosystem may prevent more medicines from being developed. The rain forest ecosystems also make poor farmland. Unlike the rich soil s of the Great Plains, where people destroyed the tallgrass prairie ecosystem, Amazon rain forest soil is thin and has few nutrient s. Only a few seasons of crops may grow before all the nutrients are absorbed.

The farmer or agribusiness must move on to the next patch of land, leaving an empty ecosystem behind. Rebounding Ecosystems Ecosystems can recover from destruction, however. The delicate coral reef ecosystems in the South Pacific are at risk due to rising ocean temperatures and decreased salinity. Corals bleach, or lose their bright colors, in water that is too warm.

They die in water that isnt salty enough. Without the reef structure, the ecosystem collapses. Organisms such as algae, plants such as seagrass , and animals such as fish, snakes, and shrimp disappear. Most coral reef ecosystems will bounce back from collapse. As ocean temperature cools and retains more salt, the brightly colored corals return. Slowly, they build reefs. Algae, plants, and animals also return. Individual people, cultures, and governments are working to preserve ecosystems that are important to them.

The government of Ecuador, for instance, recognizes ecosystem rights in the countrys constitution. The so-called Rights of Nature says Nature or Pachamama [Earth], where life is reproduced and exists, has the right to exist, persist , maintain and regenerate its vital cycles, structure, functions and its processes in evolution.

Every person, people, community or nationality, will be able to demand the recognitions of rights for nature before the public bodies.

Ecuador is home not only to rain forest ecosystems, but also river ecosystems and the remarkable ecosystems on the Galapagos Islands. Ecocide The destruction of entire ecosystems by human beings has been called ecocide, or murder of the environment.

Human Ecosystem "Human ecosystem" is the term scientists use to study the way people interact with their ecosystems. The study of human ecosystems considers geography, ecology, technology, economics, politics, and history. The study of urban ecosystems focuses on cities and suburbs. The Coral Triangle stretches from the Philippines in the north to the Solomon Islands in the east to the islands of Indonesia and Papua in the west.

Bactrian and Dromedary Different desert ecosystems support different species of camels. The dromedary camel is tall and fast, with long legs. It is native to the hot, dry deserts of North Africa and the Arabian Peninsula. The Bactrian camel has a thicker coat, is shorter, and has more body fat than the dromedary. The Bactrian camel is native to the cold desert steppes of Central Asia.

It is easy to tell the two types of camels apart: Dromedaries have one hump, Bactrians have two. Also called maize. Seaweed can be composed of brown, green, or red algae, as well as "blue-green algae," which is actually bacteria.

Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment.

Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor.

Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor. There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support. Teach your students about limiting factors with this curated collection of resources.

Trophic levels provide a structure for understanding food chains and how energy flows through an ecosystem. At the base of the pyramid are the producers, who use photosynthesis or chemosynthesis to make their own food. Herbivores or primary consumers, make up the second level. Plants and lichens are the primary producers on land. Trees, shrubs, vines, grasses, mosses and liverworts are the primary producers in temperate and tropical climates.

In the Arctic, where plants are not as well equipped to survive, lichens — symbiotic organisms made up of photosynthesizing algae or cyanobacteria and fungus — are the primary producers. In the temperate and tropical zone, a food web may begin with grass, for example. The grass grows by converting energy from the sun and carbon dioxide into its tissues and stored carbohydrates. A caterpillar nibbles on the grass but ends up being eaten by a bird.

A predatory cat then eats the bird. When the big cat dies, its body decomposes with the help of decomposers and provides inorganic molecules that in turn feed the plant producers in the ecosystem. In the Arctic, this theoretical life web is usually shorter.

Lichen grows on a rock, reindeer eat the lichen, and then when the reindeer die their bodies nourish scavengers and decomposers. Algae is a broad grouping of aquatic plants or plantlike organisms that contain chlorophyll. They are the basis of all aquatic life webs. Though algae often resemble terrestrial plants, they lack structures such as stems, leaves and roots.

Furthermore, algae can range from tiny unicellular organisms like diatoms microalgae to large multicellular organisms like kelp macroalgae. In a marine food web, algae are the foundation. Phytoplankton, a variety of single-celled algae, are consumed by zooplankton, which are then consumed by crustaceans, fish and whales.

The crustaceans, fish and whales are in turn consumed by other organisms including humans. They do this by releasing enzymes onto the dead matter and afterwards, consume the broken down substances.

They form a vital role in the recycling of matter. When organisms die and decompose plants absorb the broken down nutrients through their roots. Producers, consumers and decomposers Producers and consumers Feeding relationships show what organisms eat or are eaten by others and through this the levels of organisation in an ecosystem.

Decomposers Decomposers are bacteria and fungi, which break down dead organisms in a process called decomposition or rotting. Organism How it gets energy Producer Photosynthesis Primary consumer Eat the producers, most are herbivores Herbivores Eat only plants Secondary consumer Eating primary consumers, most are carnivores Carnivores Eat only other animals Tertiary consumer Eating secondary consumers Omnivore Consumers which eat both animals and plants so can occupy more than one trophic level in a food chain Decomposer Feeding on dead and decaying organisms and on the undigested parts of plant and animal matter in faeces.
