Explanation:
The productivity of an ecosystem refers to the rate at which energy is produced and stored as biomass by plants through photosynthesis. The productivity can be measured in terms of the amount of organic matter produced per unit area per unit time. The correct sequence of ecosystems in the order of decreasing productivity is as follows:
- Mangroves: Mangroves are highly productive ecosystems found in coastal areas. They have a high rate of photosynthesis and support diverse plant and animal life. The dense vegetation of mangroves provides a rich source of organic matter, which makes them highly productive.
- Grasslands: Grasslands are also productive ecosystems, characterized by a variety of grass species. They receive a moderate amount of rainfall, which supports the growth of grasses. Grasslands are home to a wide range of herbivores and support grazing animals.
- Lakes: Lakes are freshwater ecosystems that can vary in productivity depending on various factors such as nutrient availability and sunlight penetration. Lakes receive nutrients from surrounding land and are also influenced by the productivity of their catchment area. They support a variety of aquatic plants, algae, and fish.
- Oceans: Oceans are the largest and most diverse ecosystems on Earth. They have a lower productivity compared to the previous ecosystems mentioned. The primary productivity in the oceans is largely limited by nutrient availability, particularly nitrogen and phosphorus. Phytoplankton, which are microscopic algae, are the primary producers in the ocean and form the base of the marine food chain.
Summary:
The correct sequence of ecosystems in the order of decreasing productivity is: Mangroves, Grasslands, Lakes, Oceans.
