Aquatic Ecosystem
A community of plants and animals that live in water.
What is it?
An aquatic ecosystem is a habitat in water. It can be freshwater (like rivers and lakes) or saltwater (like oceans). The aquarium you saw is a small aquatic ecosystem. It has fish, plants, and tiny particles like plankton that are part of the food web. Every living thing in the water depends on others for food and clean water. Tropical freshwater fish are part of a freshwater aquatic ecosystem. The aquarium mimics a natural ecosystem to help the fish thrive. The sunfish you saw is part of a freshwater aquatic ecosystem. Sunfish help control insect populations and are an important part of the food web.
Why it matters
Aquatic ecosystems are important for the planet. They provide food, oxygen, and clean water. They are also home to many animals. Learning about them helps us protect rivers, lakes, and oceans.

水生生态系统
生活在水中植物和动物的群落。
它是什么？
水生生态系统是水中的栖息地。它可以是淡水（如河流和湖泊）或咸水（如海洋）。你看到的鱼缸是一个小型水生生态系统。里面有鱼、植物和像浮游生物这样的微小颗粒，它们是食物网的一部分。水中的每个生物都依赖其他生物获取食物和清洁的水。热带淡水鱼是淡水水生生态系统的一部分。鱼缸模仿自然生态系统，帮助鱼类茁壮成长。你看到的太阳鱼是淡水水生生态系统的一部分。太阳鱼帮助控制昆虫数量，是食物网的重要组成部分。
为什么重要
水生生态系统对地球很重要。它们提供食物、氧气和清洁的水。它们也是许多动物的家园。了解它们有助于我们保护河流、湖泊和海洋。
