Celebrating Hispanic & Latinx Heritage Month

Celebrate Hispanic & Latinx Heritage Month

This project is a part of the Hispanic & Latinx Heritage Month celebration because it supports a Latino teacher or a school where the majority of students are Latino.

My Project

Maintaining cultures of phytoplankton and zooplankton, such as Daphnia, rotifers, and copepods, is crucial for a healthy and balanced aquarium ecosystem, particularly in a marine biology classroom setting where students are learning to care for a diverse range of animals, including fish, echinoderms, mollusks, and arthropods. Phytoplankton serve as the primary producers, forming the base of the aquatic food web by converting light energy into organic matter through photosynthesis. This not only provides a direct food source for zooplankton but also helps maintain water quality by consuming carbon dioxide and releasing oxygen. Zooplankton, on the other hand, play a pivotal role as primary consumers. Daphnia, rotifers, and copepods feed on phytoplankton and, in turn, serve as a nutritious food source for many aquarium inhabitants, including fish larvae and small invertebrates. This natural feeding strategy promotes growth and vitality among aquarium animals and mimics their natural diets more closely than artificial feeds.

The presence of these live cultures helps students observe and understand the complex interactions within aquatic ecosystems, from energy transfer to nutrient cycling, and fosters a hands-on appreciation for marine biology.

The decomposition of uneaten phytoplankton and zooplankton contributes to nutrient recycling, promoting a balanced aquarium environment. Integrating these live cultures into a marine biology classroom not only supports the health of the aquarium inhabitants but also enriches the educational experience by demonstrating ecological principles and the importance of biodiversity in maintaining robust and resilient ecosystems.
