I am so bad at writing and I was wondering if someone could check this over for me, I am happy to be criticized! Thanks!

Frogs are important because they devour bugs which helps keep the ecosystem in balance. Without Frogs there would be no research.
Their skeletal, muscular, digestive, nervous, and other parts of their body are very similar to other animals. They are a vital part in medical research to test new drugs. Students dissect them to have a better understanding of anatomy. If something ever happened to the frogs it would affect us.

Frogs are cold blooded which means they are amphibians. Until they become adults frogs become tailless. Generally frogs live in tropical regions they survive both on land and water. Frogs skin is usually smooth and moist this is because their skin absorbs water into their bodies so that they don’t have to drink water. Naturally frogs are different from us humans; their heart has three chambers unlike ours which has four chambers. The male frogs have a vocal sack which is used to attract female frogs.

When female frogs become pregnant, they lay there eggs in water; the eggs are covered in a jelly substance. With in three to twenty-five days the eggs hatch. When they are born they are called tadpoles, they live in the water for now. They have gills and a tail, they look very similar to fish. As time goes by there hind legs start to form first, then their front arms. They can not go on land yet because they will die. It takes a tadpole two weeks to a few months to become an adult. Finally when the tadpole is fully developed, tailless it will be able to go on land. It hops on land for the first time, and then it becomes an adult.

Since the frog can go on land and water it has more enemies than before. Bats, Heron, Fish, Raccoons, Turtles, snakes, and humans are some of its biggest enemies. The frog is flat headed, it has external eardrums and bulging eyes to see and hear his enemies. In order to protect its self from being eaten the frog camouflages itself or gives out a poison. The frog’s diet consists of worms, spiders and minnows. They eat their prey in one piece, because they only have teeth on their upper jaw; they hunt at night. Their strong hind legs help them jump and get their prey with their sticky tongue .Frogs enjoy eating insects.

Frogs are important because they provide food to people all over the world. They eat insects which is very beneficial to farmers and gardeners. Frogs provide nutrients to ponds, lakes and land. Frogs become prey to birds, mammals and reptiles and without them many animals would die; even humans would die. They are part of the ecosystem and if something happened to the frogs it would affect us. Someway somehow, we are all connected in the web of life.

Sure, I can help check your writing for you! It seems like there are a few areas where you could make some improvements.

First, let's address some grammatical issues. When referring to insects, you can use the word "insects" instead of "bugs" to be more specific. Additionally, make sure to use proper capitalization, such as starting sentences with a capital letter and capitalizing proper nouns like "Frogs."

In terms of sentence structure, there are a few run-on sentences that you can correct. For example, in the sentence "Frogs are cold-blooded which means they are amphibians," you can insert a comma after "cold-blooded" to separate the two clauses. Similarly, in the sentence "Frogs skin is usually smooth and moist," you can insert a comma after "Frogs" to separate the subject and verb.

Additionally, there are a few areas where the pronouns you use can be clearer. For instance, in the sentence "If something ever happened to the frogs it would affect us," it's not immediately clear what "it" refers to. To improve clarity, you can rephrase it to say "If something ever happened to the frogs, their absence would affect us."

Finally, it may be helpful to organize your ideas into separate paragraphs. This will make it easier for your readers to follow along with your points and arguments.

Overall, don't be discouraged! Writing is a skill that can be improved with practice. Consider revising your writing using the suggestions above, and it will help improve the clarity and flow of your ideas.
