Answer:
1.Ecologists often estimate the size and density of. populations using quadrats and the mark-recapture method.
2. The two key components of ecosystem stability are resilience and resistance.
3.The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) affect population
4. When the climate is changing in the colder direction it effects the planet in the opposite way than it does when it is changing in the warmer direction. Ad nauseam the contemporary, it’ll keep getting hotter and at a greater rate so the ecosystem is going to die.

Explanation:
potential energy is the correct answer
Temperature. In case you have ever baked, you can relate to this. For example, when you make caramel, you simply put the caramel on a boiling hot pan and sit back and watch it. It always goes fastest this way.
Typical household bleach has a value of pH of 13, so the concentration of H₃O⁺ in household bleach is 1 × 10⁻¹³ M.
<h3>What is pH?</h3>
pH of any solution is defined as the negative logarithm of the concentration of H⁺ ion presnt in the solution.
pH = -log[H⁺]
From this equation we can calculate the concentration of H⁺ ion by removing logarithm as:
[H⁺] = 
Given value of pH = 13
[H⁺] = 10⁻¹³ M
Hence, required concentration is 1 × 10⁻¹³ M.
