As herbivores that lack any serious natural predators, kangaroos participate in very simple food chains composed of themselves, their grass-like food and the scavengers and decomposers that eat them. Humans historically hunted and killed many kangaroos, but they are relatively safe from unarmed predators.Know More
Because they consume vegetation directly, kangaroos are considered by scientists to be primary consumers. Kangaroos are grazers that share similar diets with the large ungulates of North America. They primarily consume grasses, but they will eat forbs and herbs as well. In captivity, kangaroos may accept fruit, but this is not part of their diet in the wild.
Dingoes occasionally hunt and eat kangaroos, but this is not a common occurrence. Kangaroos are blessed with great speed and a fierce disposition; few predators are capable of catching them or are foolish enough to fight them. However, once kangaroos die, like all other organisms, they are consumed by scavenging and decomposing organisms. Vultures, rats and insects scavenge the bodies of the dead kangaroos after they die. Shortly thereafter, decomposers in the form of earthworms, fungi and bacteria break down the cells of the kangaroos. This liberates the resources in the kangaroo’s body so that plants can use them to fuel their growth.Learn more in Pets
Sharks are apex predators, feeding on turtles, fish, seals, crabs and mollusks. They have adapted to feed on virtually everything in their environment. Their predation is a crucial element in maintaining population in different areas of the ocean, preventing prey animals from overgrazing any one area.Full Answer >
According to Nature.com, the golden eagle is at the top of the food chain, above plants, squirrels and scorpions. Plants are considered primary producers and make up the first level of the food chain. Ground squirrels, which are primary consumers, are in the second level and feed on plants. Golden eagles are tertiary consumers, meaning that they prey upon primary and secondary consumers.Full Answer >
A food web is a comprehensive map of how energy moves, in the form of food, throughout an ecosystem, while a food chain is one specific path through the web. Most food webs on Earth derive their energy primarily, if not exclusively, from sunlight. That energy is captured by plants via photosynthesis and then distributed to the consumers in the environment.Full Answer >
A food chain is a simple sequence of organisms in which each animal or plant is dependent on the one above or below it. Food webs are more complex than food chains in that they include all organisms that have similar feeding habits. Both food chains and food webs include animals that depend on each other for food.Full Answer >
