Which is true about coral reefs?

They are built by tiny invertebrate animals that have a symbiotic relationship with algae.
They are low in primary productivity
They are low in biodiversity
They are growing in size and number globally

Correct Answer

A. They are built by tiny invertebrate animals that have a symbiotic relationship with algae.

Explanation

Coral reefs are indeed built by tiny invertebrate animals called coral polyps. These polyps have a symbiotic relationship with algae called zooxanthellae, which live inside their tissues. The polyps provide a protected environment and nutrients for the algae, while the algae provide the polyps with food through photosynthesis. This mutualistic relationship allows the coral polyps to build calcium carbonate skeletons, which form the structure of the coral reef. Therefore, the statement "They are built by tiny invertebrate animals that have a symbiotic relationship with algae" is true.

One reason many salmon species have gone extinct is

Dams block their path to breeding grounds
Over fishing
Water diversion for irrigation
All of the above

Correct Answer

A. All of the above

Explanation

The correct answer is "all of the above." This means that all three options mentioned - dams blocking their path to breeding grounds, overfishing, and water diversion for irrigation - are reasons why many salmon species have gone extinct. Dams can prevent salmon from reaching their spawning grounds, overfishing reduces their population, and water diversion can disrupt their habitat and access to necessary resources. All of these factors combined have contributed to the decline and extinction of various salmon species.

Which is the best long-term strategy to saving an endangered plant species?

Store its seeds in an underground seed bank
Grow the plant at a greenhouse where it is protected
Restore its native habitat and protect the habitat
Educate the public about the plant

Correct Answer

A. Restore its native habitat and protect the habitat

Explanation

Restoring the native habitat and protecting it is the best long-term strategy for saving an endangered plant species because it addresses the root cause of the species' decline. By restoring the habitat, the plant can thrive in its natural environment, ensuring its long-term survival. Additionally, protecting the habitat from threats such as deforestation or pollution helps to safeguard the plant from further harm. This approach not only benefits the endangered plant species but also promotes the conservation of other species that depend on the same habitat.

What about whales makes them so vulnerable to extinction?

They are K selected
They migrate long distances
They have oils that are valuable to humans
All of the above

Correct Answer

A. All of the above

Explanation

Whales are vulnerable to extinction due to a combination of factors. Firstly, they are K-selected species, which means they have a low reproductive rate and long gestation periods, making it difficult for their populations to recover quickly. Secondly, their migration patterns expose them to various threats such as habitat loss, pollution, and collisions with ships. Lastly, their oils, which are valuable to humans, have led to historical overhunting and exploitation. Therefore, all of these factors contribute to the vulnerability of whales to extinction.

What does the Magnuson act allow?

The UN can police the open oceans and set fisheries quotas
The USA can police the open oceans and set fisheries quotas
The USA can patrol the ocean within 200 miles of the coast and set fisheries quotas
None of the above

Correct Answer

A. The USA can patrol the ocean within 200 miles of the coast and set fisheries quotas

Explanation

The Magnuson Act, officially known as the Magnuson-Stevens Fishery Conservation and Management Act, allows the USA to patrol the ocean within 200 miles of the coast and set fisheries quotas. This act was enacted in 1976 to protect and manage marine resources in US waters. It established the Exclusive Economic Zone (EEZ), which extends 200 nautical miles from the coast, giving the USA jurisdiction over these waters. The act also mandates the establishment of regional fishery management councils to develop and implement conservation and management measures for fisheries in the EEZ.

Which of the following species need an old-growth forest of the pacific northwest?

Panther
Salmon
Spotted owl
None of the above

Correct Answer

A. Spotted owl

Explanation

The spotted owl is a species that requires an old-growth forest of the Pacific Northwest. This type of forest provides the necessary habitat for the owl, as it relies on large, mature trees for nesting and roosting. The old-growth forest also supports the owl's prey, such as small mammals and birds. Therefore, the spotted owl is dependent on the existence of these specific forest conditions for its survival.

Which of the following is not a provision of the endangered species act?

The species must be given a protected critical habitat
A species survival is more important than human economic interests
The government cannot fund a project that would directly harm an endangered species
A person cannot hunt an endangered species

Correct Answer

A. A species survival is more important than human economic interests

Explanation

The correct answer is "A species survival is more important than human economic interests." This is not a provision of the Endangered Species Act. The Act does prioritize the protection and preservation of endangered species, but it also takes into consideration the economic impact and interests of humans. The Act allows for a balance between conservation efforts and economic development, ensuring that both are taken into account when making decisions regarding endangered species.

Which of the following is the number one reason for anthropogenic species extinction?

Poaching and overhunting
Ecotourism
Invasive species
Habitat destruction

Correct Answer

A. Habitat destruction

Explanation

Habitat destruction is the number one reason for anthropogenic species extinction. When natural habitats are destroyed or altered by human activities such as deforestation, urbanization, or pollution, it disrupts the delicate balance of ecosystems and directly impacts the survival of many species. Loss of habitat leads to loss of food sources, shelter, and breeding grounds, making it difficult for species to survive and reproduce. This ultimately results in the extinction of species as they are unable to adapt or find suitable environments to thrive in.

Which of the following fishing techniques has caused the most damage to the coastal ocean ecosystems?

Long lining
Trawling
Drift nets
Sonar fishing

Correct Answer

A. Trawling

Explanation

Trawling is the correct answer because it involves dragging a large net along the ocean floor, which can cause significant damage to the coastal ocean ecosystems. This fishing technique can destroy habitats, disrupt the seabed, and result in bycatch of non-target species. Trawling can also lead to overfishing and depletion of fish populations, further impacting the balance and health of the coastal ocean ecosystems.

What is true about the recovery of the whooping crane in the US?

They have not been successfully breeding in captivity
They are extinct
They have not been reintroduced because their habitat is toxic
They were retrained to migrate by following an airplane

Correct Answer

A. They were retrained to migrate by following an airplane

Explanation

The whooping crane in the US has been successfully recovering through a unique method of retraining. They were taught to migrate by following an airplane, which has helped in their population growth and conservation efforts. This approach has proven to be effective in ensuring their survival and increasing their numbers.

Check the box next to each statement that is true about aquaculture:

Has caused the destruction of mangrove forests
Has depleted nutrients in coastal waters
Has increased the spread of sea lice
Could lead to an increase in invasive fish

Correct Answer(s)

A. Has caused the destruction of mangrove forests
A. Has increased the spread of sea lice
A. Could lead to an increase in invasive fish

Explanation

Aquaculture, the farming of aquatic organisms, has indeed caused the destruction of mangrove forests. Mangroves are often cleared to make way for aquaculture operations, resulting in the loss of valuable coastal ecosystems. Additionally, aquaculture has been associated with an increase in the spread of sea lice. These parasites can infest farmed fish and spread to wild fish populations, causing harm to both. Furthermore, the practice of aquaculture could potentially lead to an increase in invasive fish species. Introducing non-native species into new environments can disrupt ecosystems and have negative ecological impacts.
