Which behavior is both territorial and used for courtship? (1 point) A) dance rituals with potential partners B) sparring or wrestling using antlers or horns C) baring teeth as a sign of aggression D) defending a nest from predators 2. Corrected_text: Birds display a wide variety of courtship behaviors. Which behavior is also a territorial behavior? (1 point) A) dancing and calling on a lek (communal ground) with other males, competing for female attention B) creating a bower (arch) with interesting objects and defending it from rival males C) singing a particular song to help potential mates hear them D) flashing feathers to show their health and grooming abilities 3. Corrected_text: Why is climate change a concern when it comes to animal behavior and ability to reproduce? (1 point) A) Animals may have to change their courtship behavior due to climate change, and that may decrease their success in mating. B) Some animals rely heavily on their environment for reproduction, and any changes may make it impossible. C) Changes to animals’ native environments may decrease the available habitat, reducing the space animals have to raise young. D) Food might become scarce, causing animals to search more and find less food, which uses up energy that could be put toward reproduction. 4. Corrected_text: How does hibernation allow for the survival of a group of animals? (1 point) A) Hibernation makes access to food easier. B) Hibernation reduces the energy required for survival. C) Hibernation protects the animal young from predators. D) Hibernation increases the chances of meeting a mate
The Correct Answer and Explanation is:
1. Which behavior is both territorial and used for courtship?
Correct Answer: B) sparring or wrestling using antlers or horns
Explanation:
In many species, males use sparring or wrestling to establish dominance and defend their territory, which are critical factors in courtship. For example, in species like deer, moose, and elk, males fight with their antlers to defend a territory and also to show their strength and genetic fitness to potential mates. This dual purpose of defending a territory and attracting mates through combat is common in the animal kingdom.
2. Birds display a wide variety of courtship behaviors. Which behavior is also a territorial behavior?
Correct Answer: B) creating a bower (arch) with interesting objects and defending it from rival males
Explanation:
Male birds, particularly those in species like the bowerbird, engage in territorial behaviors by building elaborate structures called bowers, which they decorate with various objects. These bowers are used to attract females and are vigorously defended from rival males. This behavior serves both to establish territory and as a display of fitness to females, combining courtship with territorial defense.
3. Why is climate change a concern when it comes to animal behavior and ability to reproduce?
Correct Answer: B) Some animals rely heavily on their environment for reproduction, and any changes may make it impossible.
Explanation:
Climate change can drastically alter the environments that many species rely on for breeding. For example, temperature shifts, changes in rainfall, or altered food availability can make traditional breeding grounds less suitable or even uninhabitable. For animals that depend on specific environmental cues for mating or raising offspring, these changes can reduce reproduction success, ultimately threatening species survival.
4. How does hibernation allow for the survival of a group of animals?
Correct Answer: B) Hibernation reduces the energy required for survival.
Explanation:
Hibernation is an energy-conservation strategy used by many animals to survive harsh winter conditions when food is scarce. By entering a state of dormancy, animals like bears, bats, and squirrels significantly lower their metabolic rate, reducing the amount of energy they need to survive. This allows them to endure long periods without food and wait for more favorable environmental conditions to return. Hibernation is critical for survival in regions with extreme seasonal changes.
