c. water
d. sunlight

Explanation:

• Question 7: A severe drought reduces available resources like water and food, which lowers the carrying capacity (the maximum number of organisms an environment can support).
• Question 8: Eliminating predators might initially seem to help, but carrying capacity is about resource - based limits. Predators are part of the biotic (living) factors, but their removal doesn't increase the actual resources (like food, water, space) that determine carrying capacity. So, there is no effect on the carrying capacity.
• Question 9: Habitat destruction reduces the living space and available resources (biotic and abiotic) for organisms, thus decreasing the carrying capacity.
• Question 10: A disease outbreak can kill many organisms, reducing the number of individuals an environment can support (lowering carrying capacity). Abundant food, plenty of space, and lack of competition are factors that can support a higher number of organisms (increase or not decrease carrying capacity).
• Question 11: Biotic (living, like plants, animals) and abiotic (non - living, like temperature, water) factors limit population growth. Organic and inorganic are chemical classifications, physical and chemical are more about the nature of substances in a non - ecological context, and natural and artificial are not the standard ecological classification of limiting factors.
• Question 12: Biotic factors are living components. Predators are living organisms. Temperature, water, and sunlight are abiotic (non - living) factors.
