Many ecological phenomena are difficult to study because they take long periods of time or have large spatial scales.
An ecosystem is a community of living organisms interacting with each other and their environment. Inputs to an ecosystem include energy from the sun, nutrients, and water, while outputs include waste products, oxygen released through photosynthesis, and energy transferred to higher trophic levels.
Life is difficult to define because it encompasses a wide range of characteristics and processes that vary among different organisms, making it challenging to come up with a single, all-encompassing definition.
A keystone species in an ecosystem is one that has a disproportionately large impact on its environment compared to its abundance. These species play crucial roles in maintaining the balance and diversity of the ecosystem. They often have unique characteristics or roles that make them essential for the health and stability of the ecosystem.
Viruses are difficult to define because they are acellular entities that can only replicate inside host cells, leading to questions about whether they are living or non-living. Additionally, viruses exhibit significant diversity in structure, genetic material, and replication strategies, making it challenging to come up with a single definition that encompasses all virus types.
A small group, or something that appeals to a small percentage of the whole population.The term niche is used to describe the role an organism or population plays within its community or ecosystem. It encompasses all relationships that the organism (or population) has with its environment and with other organisms and populations in its environment.HI my name is JEFF

The concept of organization is difficult to define because it means many different things. An organization can be a one person operation or it can be a company that has thousands of employees.

The question assumes that it is difficult to define philosophy. That's not necessarily true.Etymologically, a "philosopher" is a "lover of wisdom." In other words, a philosopher is someone seriously trying to become wise. That's not difficult to understand.If the concept of wisdom were difficult to define, then it would be difficult to define the goal of philosophy. If the concept of wisdom were not difficult to define, then it would not be difficult to define the goal of philosophy.Whether or not wisdom is difficult to define depends upon the nature of wisdom, which is controversial. Anyone who is serious about the nature of wisdom needs to articulate what he or she thinks is a sound argument concerning its nature. Whatever argument is advanced, it will be attacked to see if it stands up to examination.Therefore, it may or may not be difficult to define the nature of philosophy, because doing so depends upon understanding the nature of wisdom. If wisdom is simple, as it may be, then so will be the definition of philosophy. If it is not the case that wisdom is simple, then neither will be the definition of philosophy.In short, the nature of philosophy is itself controversial. That itself may be sufficient for it to be classified as difficult to define. ----
