Limiting Factors

Reflective questions might include:
-What were the limiting factors in the pond ecosystem?
-Which factors were caused by humans and which were natural events?
-Complete a food web for the pond and identify other species that are likely to
be affected by the loss of the frogs.
-Should the community do something to protect the frogs? Why and if so, what?

The limiting factors in the pond ecosystem is a fly that is effected/dead/ or to small.

A factor that is caused by humans can be pollution. If you pollute the air the air and the frog in heal the air it could die. By nature a fly can get a virus going to around and then if the frogs eats it the frog will die

Animals that is going to be affected the most if frogs are not going to be here is the snake. Snake is known to eats mice but if it comes across a frogs it will eat that to

I think the the community should do something because god made frogs and they don't deserve to leave

The limiting factors in the pond ecosystem was the flies. The flies that the frogs were eating was horrible. It was horrible because the flies had virus. Thats not good for the frogs. This effects the frogs land. The factors that were caused by this was the water pollution, fire, and sickness.

THE LIMITING FACTORS IS THE POND ECOSYSTEM WAS THE FLIES. THE FLIES THAT THE FROGS WERE EATING WAS HORRIBLE IT WAS HORRIBLE BECAUSE THE FLIES HAD A VIRUS. THATS NOT GOOD FOR THE FROGS. THIS EFFECTS THE FROGS LAND. THE FACTORS THAT WERE CAUSED BY THIS WAS THE WATER POLLUTION, FIRE && SICKNESS

#1.The frogs were affected because, they had a virus, polluted legs,or to small.That's why the snakes died because the frogs were sick or small.
#2.The virus was caused by a person who made the frogs area bad and dirty.When the frog was to small that was a natural event cause the frog was made like that.the polluted leg was a human event because the human messed with the frogs nature.
#3.We could put the snakes in a place were they could feed them your self

A limiting factor would be the frogs. They are a limited factor because they need a supply of food but they can’t eat every thing. They eat flies but they need to be careful on what flies they eat. They need to check if the fly viruses or if the fly is polluted. They need to make sure that the fly they eat is big enough for them. They need to check whether or not the fly is in a fire. They need to make sure that the fly is not droughty.

Viruses- human
Pollution- human
Small flies- natural
Fires- natural
Droughts- natural

If we were to take out frogs from the food chain snakes would be affected. I say this because snakes eat frogs and I don’t really know anything else that eats frogs.

I think that the community should do something about the frogs because frogs eat the flies and people don’t like flies when they go to there houses. They should try not to pollute the waters. That would also help the world too.

The limiting factors in the pond were polluted,water,hooks,viruses,fire,small fly and droughts.

The humans caused the fire,polluted water,hooks,
the natural events were viruses and
small flys droughts.

I think that they should help the frogs becaues they help the population of bugs.


The snakes would be affected if the frogs was not there.

The limiting factors in the pond ecosystem is a fly that is effected,dead or mad small.
The factors that were caused by humans was pollution. If you pollute the air and the frog breaths in the air it could probably die from the polluted air.A nature fly with an virus, if an frog eat that fly the frog could die from eating an fly with an virus.
The animal that is going to be most affected is going to be the frogs beuase the snakes eat frogs. I know the snakes eat mice but if an frog gets near a snake the snake would eat that frog up.
I think the community should do something to protect the frogs becuase the frogs dont give birth for more frogs can come to the this world to get eaten..so i think the frogs should be away from anyother animals that et frogs.

The limiting factors were the flies and the frogs, I think. The flies limitied because most of them were fine but then others had a virus or something bad wrong with them. So when the frogs eat them they die because they had a bad fly that past its diesies to the frog or something. Or the frogs got dragged in the pond because the fly was attached to a fishing hook. So the frogs were getting more and more limited because of the flies they ate.

*Flies on fire- Natural OR CAN BE human event

*Flies w/ desies- Natural

*Fishing hook flies-Human event

*Drought or pollution flies- Human event

I think the community should do something to protect frogs. They are just as important as any other animal out there and they DO get rid of flies that you think are annoying. Its just cruel to sit back and know that frogs are being killed because of most of us. So we should all stick up for them and help them live longer.

The limiting factors in the pond were
sickness,drought,small fly,fire,unhealthy water,hook

Humans:hook,fire,unhealthy water sickness.

Natural:fire,sickness,drought,small fly

I think snakes owls/birds will be affected because thats a food source that they really need for them to survive.

I think the communities should help because frogs eat flies and other insects that are over populated.

The limiting factors of a frog in the pond ecosystem is small flies.

A factor that is caused by humans is a bulldozer that could be a limiting factor for frogs. A factor that is by nature is viruses.


The community could start a foundation to keep construction workers and people to stop destroying their pond ecosystem.

The limited factors are flies. A factor that can cause by human is pollution. Pollution will make the frogs die when the air is polluted. The frogs can get eaten by a snake and the snake can get eaten by a eagle thats a food chain that can be the loss of frogs.The community can save the frogs by collecting all of the frogs and make there own aquarium.
