This lab reflected on the difference between crayfish and grasshoppers.
The Grasshopper's scientific name is caelifera. Its habitat is generally fields and grass, which they eat.Their niche is to fertilize plants with their droppings, and they are eaten by birds, lizards, spiders, and rodents.
The Crayfish 's scientific name is Astacoidea. Its habitat is in shallow or deep parts of bodies of water. It feeds on Living, dead, animals or plants. Their niche is to be an omnivoric scavenger. They are eaten by some land animals, like racoons, and bass.
The Integumentary system
In this lab we dissected an earthworm to see the organs inside.
The earthworm's scientific name is Lumbricus terrestris. They live in the soil burrowing through it. Earthworms eat the dirt they crawl through, taking out minerals and excreting the leftover dirt. Many rodents that dig in the dirt are what eat the earthworm, such as turtles, birds, and moles. Their niche is to create holes in the earth for the roots and plants to grow.
In this lab, we dissected a perch where we cut it open to view the inside.
The perch's scientific name is perca flavescens, and its habitat is in freshwater lakes or rivers. Depending on their size, perch eat anywhere from plankton to sea worms or leeches. Their niche is to prey on plankton, shellfish, small fish and small larve. their predators include bass, catfish, and some birds
