Question

Which event would probably NOT occur if all of the decomposers could be removed from a temperate forest ecosystem?

Question 1 options:

The soil quality would drop and some plants would gradually begin to die.

Plants would benefit from decreased competition with mushrooms


Discarded leaves and dead animals would pile up.

Competition for food would increase among animals in the food chain.
Answer
Wild hogs introduced to Texas from Europe became feral after the hogs escaped from the ranches where they lived. Feral hogs are omnivores that feed on native plants, crops, and small animals. Feral hogs can damage an ecosystem by rooting through the soil to look for food and trampling small plants.



Which types of native organisms do feral hogs most likely compete with for food sources?

Question 2 options:

Carnivores and producers

Decomposers and herbivores

Producers and decomposers

Herbivores and carnivores
Answer
Scientists used two sets of mustard seeds to study changes due to environmental conditions. One set of seeds was produced during a severe drought. The other set was produced during normal rainfall conditions. Part AWhen the two sets of seeds were grown together, the plants grown from the set of seeds produced during drought conditions formed flowers much earlier than the plants grown from the other set. Which conclusion is supported by these results?
Question 4 options:

Drought can affect future generations of some plant populations.

Drought can benefit plants that produce flowers.

Normal rainfall damages the roots of flowering plants.

Normal rainfall reduces reproduction of plant populations.
Answer
A particular bird species found in North America obtains most of its food energy by catching and eating insects. A mutation arises in this bird population that increases the length of its beak. Although many mutations are harmful, this particular mutation has increased the ability of the bird to catch and eat certain insects. Formulate the MOST LIKELY outcome resulting from this mutation.

Question 6 options:

Other bird species will be more likely to also develop pointed beaks in order to compete.

The insects that are eaten by this bird are likely to become extinct.

Individual birds with the mutation will be more likely to survive and reproduce than birds without the mutation.

Sharp pointed beaks will result in the birds eating other more unusual food items.
Answer
A farmer digs a small pond in a pasture. The farmer adds young individuals from two species of algae eating fish to the pond and plants some reeds around the edges of the pond. The farmer wants the pond to be a sustainable ecosystem. Which of the following would be most helpful in increasing the pond ecosystem's sustainability?

Question 7 options:

Decreasing the number of plant species around the edges of the pond

Introducing older fish of the same species into the population of algae?eating fish


Having a greater diversity of living organisms in the pond

Adding gravel between the water and where the reeds are planted
