Question 2

what is population?

Answer 2

Population is the organisms of one specific species living in a defined area at the same time

Question 3

Question 8

what is a food chain?

Answer 8

A food chain describes the relationship between a single producer, and its primary secondary and tertiary consumers

Question 9

A food web describes the relationship between multiple producers, and their primary secondary and tertiary consumers

Question 10

what is trophic level?

Answer 10

This is the feeding level within a food chain

Question 11

what does the pyramid of numbers represent?

Answer 11

This represents the number of individuals at each trophic level with larger numbers, consisting of producers and smaller numbers, consisting of the secondary and tertiary consumers like carnivores

Question 12

what are the advantages of the pyramid of numbers?

Answer 12

This is an easy method to obtain information about the number of individuals in an ecosystem
This also is good for comparing changes in populations within the ecosystem throughout the year between different seasons

Question 13

What are the disadvantages of pyramid of numbers?

The numbers of a specific species may be two great to accurately record
This also does not take into account the juvenile or immature forms species

Question 14

What is the pyramid of energy?

Answer 14

only 10% of the previous energy passes to the next level

Question 15

what are the advantages of the pyramid of energy?

Answer 15

The advantages is that there are no inverted pyramids. It shows the rate of production in ecosystems, and it can be compared to different ecosystems based on relative energy flows

Question 16

What are the disadvantages of the pyramid of energy?

Answer 16

it is very difficult to collect energy data, and there is always a problem in assigning a species with a specific trophic level

Question 17

how is energy lost and used?

Answer 17

Energy is lost during the transfer of heat to the environment. It is lost as feces. not ingested
Energy is used for cellular respiration and growth
