Flujo de Energía y Materia Quiz

Explain the difference between net productivity and gross productivity.

• The net productivity considers production costs, while the gross productivity does not include them.

• The gross productivity considers production costs

• The net productivity is higher than the gross productivity

• The net productivity does not take efficiency into account

What is primary production in an ecosystem?

• Primary production is the decomposition of organic matter in an ecosystem

• Primary production is the migration of animals in an ecosystem

• Primary production is the evaporation of water in an ecosystem

• Primary production in an ecosystem is the synthesis of organic matter from inorganic compounds, mainly through photosynthesis carried out by green plants and some bacteria.

Describe secondary production and its importance.

• Secondary production is the production of biomass by heterotrophic organisms that consume organic matter produced by autotrophic organisms, and is important for the transfer of energy and nutrients in ecosystems.

• Secondary production is the production of energy by autotrophic organisms

• Secondary production is the production of biomass by autotrophic organisms that consume inorganic matter

• Secondary production is not important in ecosystems

What is the albedo effect and how does it affect the climate?

• The albedo effect is the ability of a surface to absorb solar radiation, causing global cooling.

• The albedo effect is a phenomenon related to cloud formation that has no impact on the climate.

• The albedo effect is the ability of a surface to reflect solar radiation. It can affect the climate by influencing Earth's temperature, contributing to global warming if light surfaces become darker due to climate change.

• The albedo effect is a term used to describe wind speed and its influence on Earth's temperature.

What is the relationship between productivity and energy flow in an ecosystem?

• There is no relationship between productivity and energy flow in an ecosystem.

• Productivity tends to increase with higher energy flow in an ecosystem.

• Energy flow in an ecosystem does not affect productivity.

• Productivity decreases with higher energy flow in an ecosystem.

How is net productivity calculated in an ecosystem?

• Net productivity = Gross primary production - Respiration rate

• Net productivity = Gross primary production + Respiration rate

• Net productivity = Net primary production - Respiration rate

• Net productivity = Gross primary production - Respiration rate

Why is it important to measure productivity in an ecosystem?

• To determine the amount of water in the ecosystem

• To control bird migration in the ecosystem

• To measure soil temperature in the ecosystem

• To evaluate the efficiency in converting solar energy into biomass and understand the ecosystem's health.

What is the role of primary production in the food chain?

• The primary production converts chemical energy into solar energy

• The primary production is responsible for the decomposition of organic matter

• The primary production regulates the climate through photosynthesis

• The primary production is the basis of the food chain by converting solar energy into chemical energy that is consumed by other organisms.

How does secondary production relate to the biomass of an ecosystem?

• The secondary production decreases the biomass of an ecosystem

• The secondary production is independent of the biomass of an ecosystem

• The secondary production has no relation to the biomass of an ecosystem

• Secondary production is directly related to the biomass of an ecosystem, as it represents the amount of biomass produced by consumers in a given period of time.

What impact does the albedo effect have on global warming?

• The albedo effect can both mitigate and intensify global warming depending on the surface and its ability to reflect or absorb solar radiation.

• The albedo effect only affects polar regions, not global warming in general

• The albedo effect is a natural phenomenon that is not related to global warming

• The albedo effect only impacts local temperature, not global warming
