What makes one ecosystem be more productive than another?

Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.

Why Some ecosystems are more productive than others?

Why are some ecosystems or biomes more productive than others? Tropical rainforest: High productive rate because warm temp is ideal for photosynthesis, and high global productivity. Open oceans: Low rates of production, but ALOT of global productivity. … We depend on ecosystems for goods and services.

What makes an ecosystem more productive?

A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. The presence of some forms of secondary energy can also help to increase the primary productivity rate.

Why do different ecosystems have different productivity?

The largeness of primary productivity depends on the photosynthetic capacity of producers and the existing environmental conditions, such as solar radiation, temperature and soil moisture.

What determines the productivity of a community?

What determines the productivity of a community? Sunlight, water, trace elements (nitrogen) and minerals that plants can collect from the ground. … If productivity enhances diversity, one should see more species in deep tropical waters than along shallow coastlines.

Which of the following is one of the most productive ecosystems on Earth?

Coral Reef Ecosystems

“Due to their structural complexity, corals are one of the most productive ecosystems on Earth,” states Mongabay. Often called rainforests of the ocean, they support a wide diversity of marine life in various stages of growth.

Which of the following ecosystems is more productive in terms of net primary production?

In terms of net primary productivity tropical rain forest is at the top followed by coral reef, easturies and desert and ocean.

What ecosystems are the least productive in the world?

The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.

Why does the primary productivity vary from ecosystem to ecosystem?

Primary productivity varies from ecosystem to ecosystem because it depends on the plant species inhabiting the area and their photosynthetic activity. It also depend on various environmental factors.

What do you mean by productivity of an ecosystem What are the types of productivity also mention the factors on which productivity of an ecosystem depends?

In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m2 d1). The unit of mass can relate to dry matter or to the mass of generated carbon.

Are ecosystems least productive?

Least productive ecosystem is desert and deep lake.
