Mutualism is a symbiotic relationship in which both species benefit. In commensalism, one animal typically uses another for a purpose other than food. The cattle egret benefits by eating up the insects, but the livestock. As this happens Cattle Egrets follow the livestock and eat the insects. Which kind of This is commensalism because only the Cattle Egrets are benefitting from the relationship. Most land animals hunt in packs to get to a common goal, food . Cattle egrets sometimes hunt like other wading birds, catching fish and frogs along the water's edge. But, most often, they follow herds of livestock to eat the.
As cattle graze on the field they stir up insects from the ground. As this happens Cattle Egrets follow the livestock and eat the insects.
Which kind of symbiosis is this? This is commensalism because only the Cattle Egrets are benefitting from the relationship. The horses, cows, and sheep are not affected. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control.
Explain why or why not. If why not what kind of relationship is it then. This is not parasitism because neither organisms are harmed in this relationship. This is actually Mutualism because both animals benefit. How does the limiting factor of an ecosystem affect the carrying capacity? Food, Environment, Water, and Space. If any one of them will be gone, say if food is gone, the carrying capacity is not going to be affected since the population will go down. But if all of the factors are available, the carrying capacity Vultures find and eat dead animals and plants.
Is it a decomposer or a scavenger? The vulture is a Scavenger because its not breaking the animals down. It only eats the animals.The Cattle Egret rides a Buffalo
Give an example of cooperation in a ecosystem. In an ecosystem animals cooperate for basic needs like food and shelter. For example a pack of wolves cooperate by hunting for food in packs.
Mystery bird: Cattle egret, Bubulcus ibis
Give 3 examples of predatation in an ecosytem. Bird eats the worm, the frog eats the fly, and the lion and gazelle. What does a decomposer do?

Also explain how it affects the ecosystem. There are various forms of symbiosis, including: A symbiotic relationship in which both species benefit. A symbiotic relationship in which one organism benefits and the other is not affected. A symbiotic relationship in which one organism benefits but the other is harmed. The seed heads burs of burdocks are long spines with hooked tips.

The hooked tips catch onto the hair of passing vertebrates cows, deer, dogs, humans and are carried elsewhere until they finally fall off or are pulled off by the carriers. The milkweeds contain a group of chemicals called cardiac glycosides. Cardiac glycosides are poisonous to vertebrates although not to invertebrates.
The butterflies store these cardiac glycosides. If a bird or other vertebrate such as a mouse or frog eats a Monarch it finds them distasteful and is later sick.
Experimentally vertebrate learn to avoid Monarchs butterflies. The egrets benefit from the arrangement, but the livestock, generally, do not.
It develops root-like structures from its stem which penetrate the surrounding trees and take water from the water-carrying vessels.
