What are the two ocean regions that produce the most primary productivity?

What are the two ocean regions that produce the most primary productivity?

Temperate: Coastal areas tend to have more primary productivity because more nutrients from rain run-off and because shallow water keeps them from sinking below the productive zone.

What is the main product of primary production How do scientists measure it?

The main products of primary production are carbohydrates. How do scientists measure primary production? Scientist measure primary production by turning the amount of carbon into living things. The more carbons per square, the more productive the ecosystem is.

Why are coastal regions more productive?

The proximity to land and its nutrient sources, the interception of sinking organic matter by the shallow seafloor, and the propensity for coastal upwelling all result in highly productive ecosystems.

What factors limit primary productivity?

Production varies among ecosystems, as well as over time within ecosystems. Rates of production are determined by such factors as climate and nutrient supply. Precipitation is the dominant control worldwide, but nutrient availability often limits primary production in any particular, local system.

Why is energy required for life?

All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments; metabolism is the set of the processes that makes energy available for cellular processes. The transport, synthesis, and breakdown of nutrients and molecules in a cell require the use of energy.

Why is energy required for life quizlet?

Inside every cell of all living things, energy is needed to carry out life processes. Energy is required to break down and build up molecules and to transport molecules across plasma membranes. By breaking the chemical bonds in glucose, cells release the stored energy and make the ATP they need.

What factors affect productivity in the ocean?

Ocean Productivity. Abiotic factors like solar radiation and nutrients, and biotic factors like zooplankton predation may affect ocean primary productivity. Productivity varies with the season, and also locally and globally.

Where is most marine life?

coastal habitats
Most ocean life can be found in coastal habitats on the continental shelf, even if this area occupies only 7% of the total ocean area. Most of the open ocean habitats are found in the deep ocean beyond the edge of the continental shelf.

What is the key difference between primary productivity and net primary productivity?

What is the key difference between primary productivity and net primary productivity? Net primary productivity represents just the energy used to build biomass. Net primary productivity is a small fraction (often ~10%) of primary productivity.

How do living things create energy?

Organisms mainly use the molecules glucose and ATP for energy. The flow of energy through living things begins with photosynthesis, which creates glucose. In a process called cellular respiration, organisms’ cells break down glucose and make the ATP they need.

What are the characteristics of a non living thing?

Characteristics Of Non-living Things The important characteristics of non-living things are mentioned below: Non-living things are lifeless. They do not have cells, and there is no protoplasm which forms the basis for life to exist.

How are living things capable of producing new life?

Living things are capable of producing a new life which is of their own kind through the process of reproduction. Living things have a particular life span and are not immortal. Cellular Respiration enables living organisms to acquire energy which is used by cells to perform their functions.

Can a non living thing move on its own?

Non living things cannot move on their own. However, some non living things like a car and a bus move, but due to chemical energy provided to them by petrol, diesel, or battery which is an outside factor. Non living things do not respire and show responses to external stimuli.

How are living things different from other living things?

Here are some of them: 1 Living beings can grow and develop. 2 Living beings obtain and use energy. 3 Living beings adapt to their environment. 4 All living beings are made of one or more cells. 5 Living beings respond to their environment or stimuli. 6 All living things excrete to remove waste material from the body.
