Step-by-step explanation:
Organismal level:
Contains both biotic and abiotic factors.
Ecologist's question: How do changes in the physical environment (such as temperature or moisture) affect the behavior, physiology, and survival of individual organisms?
Population level:
Contains only biotic factors.
Ecologist's question: What factors influence the growth, reproduction, and distribution of a particular species, and how do interactions with other species (such as predation or competition) affect the dynamics of the population over time?
Community level:
Contains only biotic factors.
Ecologist's question: How do the interactions between different species in a community (such as competition, predation, and mutualism) affect the structure and function of the community as a whole, and what are the consequences of changes in these interactions for community stability and resilience?
Ecosystem level:
Contains both biotic and abiotic factors.
Ecologist's question: How do energy and nutrients flow through an ecosystem, and how do biotic and abiotic factors interact to influence the productivity and diversity of the system over time?
Biome level:
Contains both biotic and abiotic factors.
Ecologist's question: How do different climatic and geologic factors interact to create different types of biomes (such as deserts, grasslands, and tropical rainforests), and what are the characteristic species and ecological processes that define each type of biome?
