can someone please help me with these 2 questions because im losing my mind!
which of the following is an example of a cylic behavior that is seasonal?
A.running from predators
B.searching for water
C.hunting at night
D.migrating for warmth
12.in the western U.S.,ranchers aggressively killed wolves because they posed a threat to their cattle.as the wolf population declined,the deer population began increasing.as a result,the surrounding forest ecosystems experienced increasing damange.the large number of deer ravaged vegetation and destroyed young trees.the entire ecosystem became degraded until wolves became protected when they wre determined to be an endangered species.based on this information what can you infer about the role of the wolves in this ecosystem
A.they are a pioneer species
B.they are a keystone species
C.they are a prey species
D.they are a competitive species
11. D
12. I believe that this one is either D or B. I'm pretty sure this one is D too, though.
I sure don't want you to lose your mind.
1. D.
12. B.
thanks ms.sue
You're welcome, Matt.
I'd be happy to help you with these questions and explain how to arrive at the answers!
Let's start with the first question:
"Which of the following is an example of a cyclic behavior that is seasonal?"
To answer this question, you need to determine which behavior occurs in a repetitive pattern over a specific period of time. Let's analyze each option:
A. Running from predators: While some animals may have to run from predators, it's not necessarily a behavior that occurs in a cyclic, seasonal pattern.
B. Searching for water: Animals need water to survive, but again, it's not necessarily a behavior that occurs in a cyclic, seasonal pattern.
C. Hunting at night: Animals that are nocturnal, such as owls or bats, have the behavior of hunting at night. However, this behavior is not necessarily tied to a specific season.
D. Migrating for warmth: Migration, where animals move from one region to another in response to weather changes, is a behavior that occurs in a cyclic, seasonal pattern. Many species migrate to warmer areas during the colder seasons.
Based on this analysis, the correct answer to the first question is D. Migrating for warmth.
Moving on to the second question:
"Based on the information provided, what can you infer about the role of the wolves in this ecosystem?"
To answer this question, we need to understand the impact of wolves on the surrounding ecosystem, as described in the scenario:
The aggressive killing of wolves by ranchers led to a decline in the wolf population. As a result, the deer population increased since they were no longer controlled by their natural predator, the wolves. The increased deer population caused substantial damage to vegetation and young trees in the forest ecosystem. This degradation continued until wolves were protected as an endangered species.
Given this information, we can infer that the wolves play a crucial role in maintaining the balance of the ecosystem. Without the presence of wolves, the deer population grew excessively and caused damage to the surrounding forest ecosystem. This suggests that wolves are acting as a regulatory species, controlling the deer population and preventing ecological imbalances.
Based on this analysis, the correct answer to the second question is B. They are a keystone species.
I hope this explanation helps! If you have any further questions, feel free to ask!
