Question

1. what factors affect productivity in terrestrial ecosystems? 22. what factors affect productivity in aquatic ecosystems?

Explanation:

For terrestrial ecosystems, factors include sunlight availability for photosynthesis, temperature affecting enzyme - activity and metabolic rates, water availability as it is essential for plant growth and physiological processes, soil nutrients like nitrogen, phosphorus, and potassium for plant development. For aquatic ecosystems, factors are light penetration which limits photosynthesis depth, temperature influencing metabolic rates of organisms, nutrient availability such as dissolved nitrogen and phosphorus, and the presence of oxygen which is crucial for respiration.

Answer:

1. Sunlight, temperature, water, soil nutrients.
2. Light penetration, temperature, nutrient availability, oxygen.
