[Creator]
Creators are named for their ability to create their own food. They absorb energy that is normally unusable to most life forms, such as light, heat, or electricity, and convert it into usable nutrients. They are usually immobile, multiply very easily, and have a vast presence across the landscape, serving as a consistent and rich source of nourishment for other Zoa. Plants that perform photosynthesis are considered the "beginning" of the food chain, passing energy from the sun onto other creatures.
[Forager]
Foragers are creatures that feed constantly in small portions. They can be seen roaming the landscape for edible bits and pieces throughout the entire day, scarecely resting. Some species are extremely active, eating massive amounts of food to fuel their constant activity, while others may live at a leisurely pace, perpetually snacking and conserving energy for emergencies. Foragers most often eat Creators and the byproducts of Creators, such as fruits and seeds, keeping plant and fungus populations in check.
[Hunter]
Hunters are creatures that feed sporadically in large portions. Hunters may sustain themselves on single large kills for days or months at a time, or on several small kills each day, but regardless of technique, this role is defined by highly structured periods of activity and rest. Hunters can be seen dedicating portions of their day to involved feeding, taking advantage of the most ideal conditions, then disappearing for long periods to recover. They are balancing forces that often prey on Foragers, preventing populations from exploding and decimating Creator populations.
[Custodian]
Custodians are the oppertunistic consumers of leftovers. They often have dynamics with Hunters and Foragers, following them and adapting to their schedules so that they may slip in afterwards and eat the parts of their meals that they left behind. Custodians are often capable of eating things that other creatures consider inedible and making use of resources that other creatures consider useless, living as a resourceful shadow of another and tidying all evidence of their activity.
[Passenger]
Passengers are creatures which inhabit the bodies of other Monstazoa. This includes the parasites, the illnesses, the benficial bacteria, the ghostly posessions, and even the thoughts and ideas. Passengers may take a parasitic approach where the host is harmed by their presence, or a mutualistic one where both the host and the passenger benefit, or something inbetween-- but without exception, Passengers absolutely require being inside or attached to a living counterpart in order to survive.
[Landscaper]
Landscapers are creatures who's natural behaviors cause massive changes to the abiotic landscape. This includes creatures which change the chemical composition of the soil, water, and air passively as a byproduct of their feeding, as well as those that conciously alter their surroundings by moving objects and building structures. The impact of Landscapers is sometimes so immense and intrinsic to the habitats in which they live that their actions go entirely unnoticed.
[Helper]
Helpers are creatures which exist as an essential component of another species' life cycle. This role can include pollinators who cross-pollinate plants as a byproduct of their feeding, farmers who purposely encourage the propogation of another species for some personal benefit, or even those whos shed shells or corpses serendipitously provide habitat for other species. Helpers are creatures of a highly diverse role that encompasses many completely unique interactions that occur nowhere else on the planet.
[Apprentice]
Apprentices are a unique role defined by their lack of ability to care for themselves. This category includes some juvenile growth stages who, at that point in their life cycle, rely on a parent to feed and protect them. It also includes domesticated species that exist virtually entirely in captivity and have no ability to survive outside of it, such as pets and livestock. Apprentices spur highly complex selfless behavior in other Zoa, who nurture their potential for an eventual reward, or sometimes for no personal benefit whatsoever.
