Food chains and food webs in aquatic systems are usually simpler and shorter than those in terrestrial biomes.

Food chains and food webs in aquatic systems can be just as complex and interconnected as those in terrestrial biomes. However, the specific structure can differ due to differences in available resources and environmental conditions. For example, some aquatic systems may have shorter food chains due to limited nutrients, while others may have longer food chains due to high productivity and abundance of prey.
