Competition involves a large number of organisms competing for a limited supply of resources

True
False

Correct Answer

A. True

Explanation

Competition in nature occurs when multiple organisms are vying for the same limited resources, such as food, water, or territory. This can lead to intense interactions and conflicts between individuals of the same or different species. The struggle for survival and reproduction drives competition, as organisms must outcompete others to secure the necessary resources for their survival and reproductive success. Therefore, the statement that competition involves a large number of organisms competing for a limited supply of resources is true.

Adaptations of predators

Claws
Speed
Fleeing
Poison

Correct Answer(s)

A. Claws
A. Speed
A. Poison

Explanation

Predators have evolved various adaptations to help them catch and kill their prey. Claws provide predators with sharp and strong appendages that can be used to grasp, slash, and tear their prey. Speed allows predators to quickly chase and catch their prey, giving them an advantage in the pursuit. Poisonous adaptations, such as venomous fangs or stingers, enable predators to inject toxins into their prey, immobilizing or killing them. These adaptations work together to enhance the predator's hunting abilities and increase their chances of successfully capturing and consuming their prey.

.............relationship between two or more species live in direct or intimate contact with on another

Correct Answer(s)
Symbiosis

Explanation
Symbiosis refers to the relationship between two or more species that live in direct or intimate contact with one another. This can include mutualistic relationships where both species benefit, such as the relationship between bees and flowers where the bees get nectar and the flowers get pollinated. It can also include parasitic relationships where one species benefits at the expense of the other, such as the relationship between ticks and mammals where the ticks feed on the blood of the mammals. Symbiosis is a fundamental concept in ecology and helps to explain the interconnectedness of different species in an ecosystem.

The following is an example of a prey adaptation

Packs
Hiding
Speed
Claws

Correct Answer

A. Hiding

Explanation

Hiding is an example of a prey adaptation because it allows prey animals to conceal themselves from predators, increasing their chances of survival. By hiding, prey animals can avoid being detected, making it difficult for predators to locate and capture them. This adaptation can take various forms, such as blending in with the environment, using camouflage, or seeking shelter in protected areas. Overall, hiding as a prey adaptation helps prey animals to minimize their risk of predation and increase their chances of survival.

Select three types of symbiosis

Predation
Mutualism
Commensalism
Predator
Parasitism

Correct Answer(s)

A. Mutualism
A. Commensalism
A. Parasitism

Explanation

The correct answer is Mutualism, Commensalism, and Parasitism. These three types of symbiosis involve different interactions between species. Mutualism is a relationship where both species benefit, Commensalism is a relationship where one species benefits and the other is unaffected, and Parasitism is a relationship where one species benefits at the expense of the other.

An interaction where both species benefit and non is harmed in the process

Predation
Parasitism
Mutualism
Commensalism

Correct Answer

A. Mutualism

Explanation

Mutualism refers to an interaction between two species where both benefit from the relationship without causing harm to each other. In mutualistic relationships, both species provide resources or services that the other species needs, resulting in a mutual advantage. This type of interaction is different from predation, where one species benefits at the expense of the other, and parasitism, where one species benefits while harming the other. Commensalism, on the other hand, is a type of interaction where one species benefits while the other is neither harmed nor benefited. Therefore, mutualism is the correct answer as it describes a situation where both species benefit without any harm.

Which of the following interaction is shown in the image?

Predator
Mutualism
Commensalism
Predation

Correct Answer

A. Predation

Explanation

The correct answer is predation. Predation is a type of interaction in which one organism, the predator, hunts, kills, and consumes another organism, the prey, for food. In the image, there is likely a depiction of one organism actively hunting and consuming another, indicating a predator-prey relationship. This interaction is a fundamental aspect of the natural world, where predators play a crucial role in maintaining the balance of ecosystems by controlling prey populations.

In mutualism one organism benefits from another and the host is hurt in the process

True
False

Correct Answer

A. False

Explanation

In mutualism, both organisms involved benefit from each other. It is a type of symbiotic relationship where both parties gain advantages. The statement contradicts the definition of mutualism by stating that the host is hurt in the process, which is incorrect. Therefore, the correct answer is False.
