Grassland decomposers are organisms that feed on decaying organic matter, breaking it down into nutrients that are returned to the soil for more plant growth. These decomposers are insects, fungi and microorganisms.Know More
Arthropods are small insects that live in the soil and decompose decaying matter. Arthropods shred organic material and then redistribute the nutrients throughout the soil. Furthermore, they help to stimulate the growth and activity of other decomposers such and fungi and microorganisms. Some arthropods found in grasslands include springtails, pseudoscorpions and rugose harvester ants. A common arthropod found in the African savannah grasslands are termites. Earthworms also act as decomposers, and they compete with arthropods for decaying matter.
Fungi is another decomposer found in a grassland biome. There are many types of decomposing fungi from mycorrhizae to Mycena aetites. Mycorrhizae is a type of fungus found in the roots of grassland plants. This fungus protects the plant from disease, enables it to absorb nutrients and helps it to tolerate drought conditions. In return, the plant provides the fungus with a food source. The majority of plants found in grasslands share a symbiotic relationship with mycorrhizae.
Mycena aetites is another species of fungus commonly found in grasslands. It feeds mostly on decaying grass and leaf litter.Learn more about Botany
Plants get their nutrients from the air, water and soil. Non-mineral nutrients, such as hydrogen, oxygen and carbon, are obtained from the air and water. There are 13 mineral nutrients important to plant growth that come from the soil.Full Answer >
Yellow leaves on petunias are caused by a deficiency in nutrients, fungal diseases, viral diseases and aphids, which are also known as plant lice. If caught early, the damaged parts of the plants can be removed and discarded. If the plant is too diseased or infested to save, the area should be replanted with new plants and fresh soil. Preventative care is the best solution for petunias.Full Answer >
Fungi are vital decomposers in the ecosystem, breaking down dead organisms and biological waste, freeing nutrients for use by other organisms and clearing away their remains. Fungi also act in partnership with some plants and algae, and are often vital to the survival of these organisms. Some species are parasites.Full Answer >
The carnivorous Venus flytrap has some very unique and useful adaptations, including digesting small animals, such as flies and spiders, to get nutrients they cannot absorb through the poor soils in their native habitats. Additionally, Venus flytraps have adapted trigger hairs on the inside of their trap pads; when triggered by a bug, the trap will snap shut, making escape impossible.Full Answer >
