Question

1. give me example of a food chain with at least 3 organisms
2. tell me what is meant by carrying capacity
3. how does carrying capacity affect a population
4. think about two examples of things that you do each day that affects the environment around you.

Answer 1

Cubanita, it helps us help you understand the question (and the answer) if you tell us what specifically you don't understand about it...

Answer 2

i basicly dont understand any of it that y i was asking for help

Answer 3

OK, starting at the top, do you know what a food chain is?

Answer 4

A food chain is somewhat a linear sequence of links in a food web starting from a trophic species that eats no other species in the web and ends at a trophic species that is eaten by no other species in the web.

Answer 5

That's a very good textbook definition. But do you understand what it is?

Answer 6

yes i understand what a food chain is. :)

Answer 7

OK, so can you think of three animals (or other organisms) which are successive links in a food chain?

Answer 8

what does that mean?

Answer 9

You just told me (correctly) that food chains are sequences of organisms which eat each other. You told me that you understand this definition...

Answer 10

yes i do understand but idk wat exactly u are asking me

Answer 11

I'm asking you what the question is asking you.

It wants you to think of three organisms such that the first organism is eaten by the second organism and the second organism is eaten by the third organism.

Answer 12

oh okay i understand now what u are asking me

Answer 13

a flower,a frog, n a snake can that work

Answer 14

I don't think frogs eat flowers. They eat insects. But snakes certainly do eat frogs.

Answer 15

oh im sorry. rat, snake and a hawk

Answer 16

Yes, that is absolutely a food chain.

Answer 17

so number 1 would be that

Answer 18

Yes. On to carrying capacity. Do you understand what carrying capacity means?

Answer 19

The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment.

Answer 20

Yes. Another textbook definition. Do you understand what it means?

Answer 21

not exactly

Answer 22

OK.

The resources available to a species in any given region are limited. There is just so much food and habitat around and it can support just a limited population of a species. The carrying capacity is the most individuals which can live in a habitat while there is still enough resources for all of them.

Clearer?

Answer 23

yes

Answer 24

Cool. So the question asks you what carrying capacity means. All you have to do is put your understanding of it in your own words.

Answer 25

oh okay that one is alot easier now after i understood it

Answer 26

The third question is very similar to the second: it asks you how the carrying capacity affects a population.

Answer 27

Clear, Cubanita?

Answer 28

Reproductive lag time is the time required for the birth rate to decline and the death rate to increase in response to resource limits.

Answer 29

Yes, but what has reproductive lag to do with the question?

Answer 30

im sorry

Answer 31

with more species in a population with little capacity there will be less birth and more dieing because of no food

Answer 32

Yes, exactly. And it occurs when the carrying capacity has been reached.

Do you think you're ready to go on to the fourth and final question?

Answer 33

oh okay and yes im ready for the fourth and final question

Answer 34

Do you understand what it's asking you?

Answer 35

kind of but not exactly

Answer 36

It's asking you to think of two things you do affect the environment.

Answer 37

Why don't you take a couple guesses?

Answer 38

oh okay i will

Answer 39

hair styling products example hairspray

Answer 40

Hair spray isn't really part of the natural world. And you're giving an example of how it affects you, not how you affect it.

Answer 41

oh okay

Answer 42

Do you use electricity?

Answer 43

yes

Answer 44

littering, creating pollution
cutting down trees

Answer 45

Well, electricity is generated from natural resources like fossil fuels. So as you use electricity, fossil fuels are converted to carbon dioxide which is released into the atmosphere. So for example, you affect the environment by using energy.

And yes, littering (creating one kind of pollution) and cutting down trees (and using paper products which are made from cut down trees) are both good examples of how you affect the environment, too.

Answer 46

Cool?

Answer 47

yes thank you for your help i understand everything alot better

Answer 48

are you a teacher

Answer 49

No, I'm a scientist. I'm glad you understand everything now!

Answer 50

oh wow thank you so much

Answer 51

You're very welcome!

Answer 52
