Fungi have several positive economic effects, such as consuming biodegradable waste, improving soil, acting as symbiotic organisms for various crops, generating antibiotics and other medicines, and being a food source. They also have several negative effects, including causing diseases in humans and animals and blighting crops and other plants, Fungi are an important category of life, both to human economies and to the other forms of life on the planet.
Fungi are ubiquitous, both in nature and in most human structures as well. They are a major decomposer and are thus responsible for rendering dead organic matter into usable forms for other organisms. They are also frequently harmful to humans, whether by destroying stored food, causing diseases such as athlete's foot, damaging structures or killing crops. On the other hand, fungi are not only used as food themselves but help process some alcohols, cheeses and baking.
Fungi can be either unicellular like yeasts or multicellular like edible mushrooms. Multicellular fungi have very diverse habits, but all share a similar basic structure. Their bodies are composed of tiny threads known as hyphae. These threads burrow through organic material and absorb nutrients. A large mat of hyphae is known as a mycelium.Learn More
Arthropods are a popular source of foods to humans and also have other ecological roles. Some common arthropods that are good sources of food are crustaceans such as crabs and prawns. The arthropod class of animals includes insects, which also have important ecological and economic roles.Full Answer >
Earthworms play a vital role in breaking down organic particles in soil and aerating soil, and their waste, called castings, is used by gardeners as fertilizer. They also play a role as bait in fly fishing.Full Answer >
Overgrazing can reduce edible plant life in an area, cause weeds to become more prevalent and can cause erosion of the soil. This phenomena is usually the result of too many animals living and eating in one location, but it can also be caused by poorly managed farming methods.Full Answer >
Fungi live in the soil, on forest floors, in water and even in plants, animals and the air. Fungi grow in virtually every area of the planet — they occupy tropical biomes as well as temperate zones. Fungi have different adaptations to suit the climates and conditions in which they live: some are more porous and suited for life in the rainforest and in marshy areas, while others have hard outer coverings, much like coral, which enables them to live on ocean floors.Full Answer >
