Final answer:
The temperature in terrestrial ecosystems is highest at the equator because of the 90-degree angle at which sunlight hits the earth.
Step-by-step explanation:
The temperature in terrestrial ecosystems is highest at the equator because sunlight hits the earth at a 90-degree angle on average. The direct sunlight at the equator provides more energy, resulting in higher temperatures compared to other latitudes.
Temperature is a critical environmental factor that significantly influences terrestrial ecosystems. It affects the distribution, abundance, and activity of living organisms, as well as various ecological processes. Temperature patterns in terrestrial ecosystems vary across different regions, climates, and elevations, influencing the types of plants and animals that can thrive in those areas.
