Tropical rain forest have the greatest biodiversity of any type of land ecosystem. How does biodiversity contribute to the sustainability of an ecosystem? The presence of more species with different adaptations makes it more likely that some organisms will survive an ecological disaster.
Which type of ecosystem has the greatest variation in temperature from its top to its bottom?
This ecosystem has the greatest biodiversity and greatest variation of temperature from its top to the bottom. Organisms must be adapted to live in both fresh water and salt water. estuary ecosystem ? Most plants that live in a desert ecosystem must be able to conserve water for long periods of time.
Which organism will most likely survive in a saltwater marsh ecosystem?
Glasswort , a plant tolerant to very high salt concentrations, is one of the only organisms able to survive in salt pannes. Pools are generally deeper than pannes, and retain water all year long (Molles, 2002). Salt-marsh snails and green crabs
Which ecosystem would be considered the most sustainable?
The forest ecosystem is most sustainable because most of the animals can eat other organisms.
Which organism provides oxygen and food in an ecosystem?
What Types of Organisms are Producers ? Producers form the first link of a food chain and as the name suggests, they produce food and oxygen using solar energy or chemical energy. Autotrophic plants, phytoplanktons, algae and certain species of bacteria
Is salt marsh freshwater?
Salt marshes are found at the border of saltwater bodies, like the Gulf of Mexico in Southwest Florida. This type of habitat is part of the tidal system where fluctuating water levels flood the marsh during high tide. The soil of salt marshes is similar to that found in freshwater marshes .
Why are salt marshes highly productive ecosystems?
Low or intertidal marshes are more productive than high marshes because of the increased exposure to tidal flow . Belowground production is high. Under unfavorable soil conditions, plants seem to put more energy into root production. ... Productivity declines northward as the growing season shortens.
What is a sustainable ecosystem for kids?
A sustainable ecosystem is a biological environment and series of habitats that is able to thrive and support itself without outside influence or assistance . In ideal sustainable ecosystems, everything is already provided within the ecosystem for life to survive.
What are the four characteristics of a sustainable ecosystem?
However, it actually refers to four distinct areas: human, social, economic and environmental – known as the four pillars of sustainability.
What are some sustainable ecosystems?
Long-lived and healthy wetlands and forests are examples of sustainable biological systems. ... As the earth's human population has increased, natural ecosystems have declined and changes in the balance of natural cycles has had a negative impact on both humans and other living systems.
What process produces oxygen?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
How does oxygen affect an ecosystem?
Oxygen provides the most energy to plants, animals and microbes during respiration . However, when all of the oxygen in water or saturated soil has been consumed, some microbes can substitute other compounds for oxygen, including iron, manganese, nitrate and sulfate, in a process known as anaerobic respiration.
How does oxygen move through an ecosystem?
Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO 2 ). CO 2 is then taken up by algae and terrestrial green plants and converted into carbohydrates during the process of photosynthesis, oxygen being a by-product.
Is a estuary freshwater or saltwater?
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean . Estuaries, and their surrounding lands, are places of transition from land to sea.
Why does marsh smell?
Salt marshes are coastal wetlands that are flooded and drained by salt water brought in by the tides. ... Hypoxia is caused by the growth of bacteria which produce the sulfurous rotten-egg smell that is often associated with marshes and mud flats.
What lives in a saltwater marsh?
- Blue Crab.
- Stone Crab.
- Hermit Crab.
- Mud Crab.
- Fiddler Crab.
- Horn Shell.
- Mussel.
- Grass Shrimp.
