Biological constraints

Biological constraints are things that make it difficult, or even impossible, for living things to do certain things. Imagine if you were trying to run like a cheetah, but you had small legs like a turtle - it would be really hard for you to run as fast as a cheetah, because your body just can't do it! That's a biological constraint.

For example, some animals might have strong jaws that are good for biting and chewing tough foods, but their jaws might not be able to open wide enough to eat really big things. Or birds might have wings that are great for flying, but they might not have strong enough leg muscles to walk easily on the ground.

These biological constraints come from things like the shape of an animal's body, the way its muscles and bones are arranged, and the way its organs work. Sometimes, these constraints might limit what an animal can do, but they can also help it survive by making it really good at certain things like catching prey or finding food in a certain environment.

So, biological constraints might make it challenging for animals to do some things, but they also help them adapt to their environment and thrive in their own unique ways!
