Biodiversity and Conservation Questions

Multiple choice

How does ocean pollution impact the food chain?

  1. It disrupts the balance of marine ecosystems.

  2. It accumulates in the tissues of marine organisms.

  3. It reduces the availability of food sources for marine life.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ocean pollution affects the food chain in multiple ways. It disrupts the balance of marine ecosystems by altering the abundance and distribution of species. It accumulates in the tissues of marine organisms, potentially harming their health and making them unsafe for consumption. Additionally, pollution can reduce the availability of food sources for marine life, leading to declines in populations.

Multiple choice

How does ocean pollution affect marine biodiversity?

  1. It can lead to the decline and extinction of marine species.

  2. It can disrupt marine food webs and ecosystems.

  3. It can alter the behavior and reproductive patterns of marine organisms.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ocean pollution can have devastating effects on marine biodiversity. It can lead to the decline and extinction of marine species, disrupt marine food webs and ecosystems, and alter the behavior and reproductive patterns of marine organisms. These impacts can have far-reaching consequences for the health and functioning of marine ecosystems.

Multiple choice

What is the tragedy of the commons?

  1. The overexploitation of a common property resource

  2. The pollution of a common resource

  3. The depletion of a non-renewable resource

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The tragedy of the commons is a situation in which a common property resource is overexploited because individuals acting in their own self-interest have no incentive to conserve the resource.

Correct answer
Explanation

Polar bears, sea turtles, and monarch butterflies are all highly sensitive to changes in their environment, making them particularly vulnerable to the impacts of climate change.

Multiple choice

Which of the following is NOT a primary threat to endangered species?

  1. Habitat loss and fragmentation

  2. Overexploitation

  3. Pollution

  4. Climate change
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

While pollution can have negative impacts on ecosystems and wildlife, it is not a primary driver of species endangerment compared to habitat loss, overexploitation, and climate change.

  1. Overfishing

  2. Pollution

  3. Climate change

  4. Disease
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Overfishing was the primary reason for the decline of the North Atlantic cod fishery in the 1990s, leading to a moratorium on cod fishing in many areas.

Multiple choice

The 'tragedy of the commons' refers to:
