Striped fish are affected by abiotic and biotic factors in the environment. Which of these factors is biotic?

water temperature

mineral nutrients

algae

A pond ecosystem is shown in the diagram below. Which statement describes an interaction that helps maintain the dynamic equilibrium of this ecosystem?
Which statement describes an interaction that helps maintain the dynamic equilibrium of this ecosystem?

The frogs make energy available to this ecosystem through the process of photosynthesis.

The algae directly provide food for both the rotifers and the catfish.

The green-backed heron provides energy for the mosquito larvae.

The catfish population helps control the populations of water boatman and waterfleas.

Refer to the illustration above. Level “A” is composed of

secondary consumers

primary consumers

producers

predators

The diagram represents a food chain. The arrows in the diagram indicate the

return of chemical substances to the environment

order of importance of the various organisms.

direction of energy flow through a series of organisms

direction in which organisms move in the environment.

Deforestation by burning has been described as a "double whammy" to the environment, meaning it has 2 negative impacts. Why is this description accurate?

Forest burning releases CO₂ while decreasing oxygen, which disrupts cycles

Deforestation reduces the amount of oxygen in the atmosphere, which depletes the ozone layer

Forest clearing is often followed by land development, which often leads to increased noise pollution

Deforestation increases the number of plant and animal species by destroying habitat

The amount of energy that usually transfers from one trophic level to the next...

Which will most likely cause an increase in the frequency of genetic mutations in humans?

increased exposure to mold spores in the air

increased exposure to the rising levels of atmospheric CO2

increased exposure to bacteria in drinking water

increased exposure to X-rays

Lowered the activation energy

15.

Which of the following would be the most likely effect, if there were a sudden increase in the cricket population?

There would be a decrease in the small bird population.

There would be a decrease in the grass/flowers population.

There would be a decrease in the mice population.

There would be an increase in the grass/flowers population.

16.

Which of the following is true in a climax community?

the community will constantly evolve and change

if one species dies, a new species will fulfill the same role

They are stable for a long time, with the same species maintaining their population

it goes through a major change called "climax" every few hundred years

17.

What type of succession is shown going from figure A to figure B?

primary succession

ecological succession

secondary succession

intermediate

In the mid-1980s an aggressive strain of algae known as Caulerpa was accidentally introduced into the Mediterranean Sea when a seaside aquarium cleaned out its tanks. The algae contains a toxin that prevents native herbivores from consuming it. Caulerpa quickly spread over the sea floor, crowding out many species including sponges, corals, sea fans, and lobsters. Which statement explains the most likely impact Caulerpa has had on the biodiversity in the Mediterranean Sea?

The presence of Caulerpa within an ecosystem is an indicator of the ecosystem’s health.

The spread of Caulerpa improved the habitat for many species of sea grasses, and increased the biodiversity.

Caulerpa interbred with native species with the same adaptations within the ecosystem.

Caulerpa became dominant within the ecosystem and reduced the biodiversity.

Scientists are studying the effects of climate change on the Baltic Sea. Some scientist predict that if current trends continue, the Baltic sea will become less salty, and it will contain less dissolved oxygen. As a result of theses changes, the Baltic Sea will have less biodiversity. The location of the Baltic Sea is shown on the map below. Which statement best explains why biodiversity in the Baltic Sea could decrease f these changes occur?

Fewer types of plants and animals are found in warm water than in cool water.

Plants and animals adapted for living in saltwater will grow more slowly in water that has less salt.

Plants and animals adapted for living in saltier conditions will not be able to survive and reproduce.

Animals adapted for living in warm water will eat all of the plants and animals adapted for living in cool water.
