11.1 Study Guide

Question 1

Biomass

Answer 1

matter from recently living organisms which is used for bioenergy production

Question 2

Productivity

Answer 2

the rate at which energy is added to the bodies of a group of organisms (such as primary producers) in the form of biomass

Question 3

Efficiency

Answer 3

describes the efficiency with which energy is transferred from one trophic level to the next

Question 4

Inputs and outputs of:
Photosynthesis

Answer 4

Carbon dioxide and water are inputs of photosynthesis. Oxygen and sugars are outputs.

Question 5

Respiration

Answer 5

Glucose and oxygen as inputs, and produces carbon dioxide, water, and energy (ATP) as outputs.

Question 6

What type of organisms perform the processes of photosynthesis and cellular respiration

Answer 6

Plants and many other photosynthetic organisms can perform both photosynthesis and cellular respiration.

Question 7

What is shown in a pyramid of energy vs. a pyramid of numbers vs. a pyramid of biomass

Answer 7

A biomass pyramid shows the amount of living matter at each trophic level, while an energy pyramid shows the amount of energy transferred. Biomass and energy pyramids are two different ways of representing the flow of energy and matter through an ecosystem.The pyramid of energy shows the rate of energy flow and/or productivity at successive trophic levels. The pyramid of numbers shows the relationship between producers and consumers at successive trophic levels in terms of their number.

Question 8

Explain why it is considered more efficient to eat at a lower trophic level vs. a higher trophic level

Answer 8

Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain.

Question 9

Predict how the amount of solar energy in a location relates to productivity

Answer 9

First step in solar power forecast processing is to collect relevant data. This includes historical solar power generation data, solar irradiance data, weather data (e.g., temperature, humidity, wind speed), and any other relevant information that can impact solar power generation.

Question 10

Predict how the amount of solar energy in a location relates to biomass
