r-strategist are species that have large offsprings, but spend no time in parental care. Sea turtles can be considered exaples of r-strategist species.
What are r and k strategists?Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.
r strategist species have a high growth rate per capita, and low competition capabilities. This is why they can colonize new environments. But they can not compete with new-established species. r species are often displaced by k species.These species are mostly small-sized organisms with short life cycles. They reach sexual maturity early and have numerous descendants spending no time or energy in parental care.
k strategist species have a low growth rate per capita, but they are big competitors with the capacity of displacing other species and monopolizing the available resources.These are big-sized species that live for a long time, reaching sexual maturity in the advanced stages of their lives. They do not have numerous progenies, but they spend time parenting.
r and k strategies are closely related to reproductive strategies, habitat selection, and dispersion ability.
Considering this difference, we can assume sea turtles are r strategist.
They lay several eggs and leave them on the beach. They spend no energy in parenting. Even though they are buried, eggs are still in danger of being attacked by predators.When little turtles emerge, they have to manage to go to to the sea by themselves, being exposed to other predators.The strategy is to spend more energy in laying several eggs to increase survival probabilities, and less energy in parenting.

Explanation:
Explain why organisms that have a narrow temperature tolerance range will be more susceptible to climate change.
Answer:
Organisms that have a narrow temperature tolerance range cannot survive in a wide variety of temperatures. Even small changes in climate can affect organisms that do not have a high tolerance for change. These organisms will be forced to adapt, relocate, or die off. If climate change is widespread, such organisms may not be able to survive.
Explanation:
edg2020
These organisms are known as stenothermal , since they are restricted to narrow range of temperature, any change in temperature would affect them significantly.
What are stenotherms?A stenotherm is a species or living organism only capable of living or surviving within a narrow temperature range. The opposite is a eurytherm, an organism that can function at a wide range of different body temperatures.
Stenothermal creatures require environments that maintain a constant temperature throughout the year in order to survive. They can only function within a very specific temperature range. Polar regions and tropical regions both have a temperature range that is rather small.
Crustaceans, insects, salmon, penguins, pythons, and other animals, such as these, are all examples of stenothermal species.

Explanation:
Local winds are basically of two types:-
Land BreezeSea BreezeThe sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.
For example, hot land temperatures next to cold ocean temperatures will create a stronger sea breeze than land temperatures that are only a little bit warmer than the ocean temperatures. So during the afternoon when the temperatures differences are normally at their highest, the sea breeze will normally be at its strongest, bringing relief from the heat to beachgoers.
This process also works in reverse at night. Only this time it is known as the land breeze. The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind.
