We just finished studying that last year and i am positive that the answer is food web. Hope that I have been able to help you.
I'm a food expert. Very good question. Iam not sure I think that i will have to talk to some of my friends about that one.
Food web
Epistasis refers to the interaction between alleles at different genes, not chromosomes. It occurs when the expression of one gene is affected by one or more other genes, leading to an alteration in the expected phenotypic ratios. This genetic interaction can influence traits in complex ways and is a key factor in the inheritance patterns observed in various organisms.
Humans are more complex organisms.
Simple Organism some simple organisms are made of single cell. Others are made of many cells that are similar Complex organisms in complex organisms, cells are organized into tissues, which make up organs. Organs form organ systems.
Inter-special social interaction between intelligent Mollusks ( octopus, cuttlefish) is mainly visual. Thus they need complex eyes to communicate.
advantages of human beings are complex organisms
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
Most interactions between organisms occur in the biosphere because it encompasses all ecosystems on Earth, providing the necessary environments for diverse life forms to coexist and interact. The biosphere includes various habitats—such as forests, oceans, and deserts—where organisms engage in relationships like predation, competition, and symbiosis. Additionally, the biosphere facilitates the exchange of energy and nutrients, which is essential for sustaining life and promoting complex interactions among species.
Galls are abnormal growths that form on plants in response to various stimuli, often caused by insects, mites, fungi, or bacteria. These organisms induce the plant to produce extra tissue, creating a protective environment for themselves. While galls can sometimes harm plants by diverting resources, they also provide a habitat for the organisms inside, showcasing a complex interaction between plants and their pathogens or pests.
System
Complex organisms evolved from simple organisms, so simple organisms evolved first.
