Sponge biomarkers

Sponge biomarkers are like special growth charts that scientists use to study sponges. Just like how your doctor measures your height and weight to see how you're growing, scientists use sponge biomarkers to understand how sponges are changing in different environments.

So, what are sponges? Sponges are creatures that live in the ocean and attach themselves to rocks and coral reefs. They look like fluffy trees with lots of holes and can come in many different colors and shapes.

Scientists use sponge biomarkers to study how different environmental factors, like pollution or changes in temperature, affect the growth and health of sponges. They do this by measuring the chemicals and molecules that the sponges produce in response to their environment. This helps them understand how these factors can impact the overall health of the ocean ecosystem.

Overall, sponge biomarkers help scientists keep track of how healthy the ocean is and how it is being affected by different environmental factors. Think of it like checking up on the growth and health of a tree in your backyard- scientists are just doing it on a much larger scale with sponges in the ocean!
