Single Celled Producers

Back

Phytoplankton are microscopic organisms that live in watery environments and can photosynthesize, making them primary producers in aquatic ecosystems.

Front

To Drift

Back

Plankton refers to small organisms that drift in water currents, including both phytoplankton (plant-like) and zooplankton (animal-like).

Front

Only planktonic for a short phase of their life.

Back

Meroplankton are organisms that spend only a part of their life cycle as plankton, typically in larval stages.

All of the abiotic and biotic factors under the Blue Heron Bridge

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

Electrons and Protons

Back

Sub Atomic Particles are the fundamental components of atoms; electrons are negatively charged, while protons are positively charged.

Front

What are the primary producers in aquatic ecosystems?

Back

Phytoplankton are the primary producers, converting sunlight into energy through photosynthesis.

Front

What is the role of zooplankton in aquatic food webs?

Back

Zooplankton serve as primary consumers, feeding on phytoplankton and transferring energy to higher trophic levels.

Front

Define meroplankton.

Back

Meroplankton are organisms that are planktonic only during certain life stages, such as larvae, before becoming benthic or nektonic.

Front

What is an ecosystem?

Back

An ecosystem is a complex network of interactions among organisms and their environment, encompassing both living and non-living elements.

Front

What distinguishes phytoplankton from zooplankton?

Back

Phytoplankton are photosynthetic organisms, while zooplankton are primarily heterotrophic and feed on other organisms.
