Drosera capensis
By Skyler Wilkinson

Also known as the Cape Sundew

The Biome
The Cape Sundew thrives in the Fynbos Biome which is located in the Cape Town area of South Africa, hence the name Cape Sundew. The Fynbos Biome consists of cool wet winters and hot dry summers.
The Drosera family have adapted to thrive in high moisture levels and low nitrogen amounts in the soil. With this adaptation the Drosera family can grow in many more environments than a regular evolved plant.
Thigmotropism
The Cape Sundew has a touch response system called (the large word above). When an insect touches the sticky surface of the Cape Sundew the plant curls up suffocating the insect and bathing it in digestive juices. This touch activated system really helps to trap prey within it's grasp and allows the plant to obtain more nutrients.
The sticky trap
This is one of the most important adaptations the Cape Sundew has invoked. There are mucilaginous glands that secrete mucilage, which is a very stick substance. This adaptation feeds the plant nutrients by trapping the insect in the plant.
The Adaptations of the Cape Sundew
The Chemical Composition
The Cape Sundew's Responsibilities
The Niche
The Cape Sundew doesn't have a major role in it's ecosystem. This carnivorous plant does eat insects which can effect some pieces of the ecosystem.
Auto or Hetero?
Most plants are autotrophs using light to create sugar to feed themselves, but a insectivorous (carnivore that only eats insects) plant is different. The Cape Sundew is a heterotroph, it doesn't use sunlight to get energy.
Herb, Omni, or Carnivore?

The Cape Sundew is a pure carnivore, but more specifically an insectivore.
The effect of removal
If the Cape Sundew is removed from its ecosystem the amount of insects would increase and to some degree effect the spread of diseases through insects. This is a biotic relationship for both the amount of insects and the spread of disease.
Limiting Factors
Biotic
The amount of small insects in the area
Doesn't have any predators
Abiotic
The amount of rain
Recent floods
Drought
Interdependent Relationships
A Interdependent relationship is often not a two way street, often it's one sided
The Cape Sundew
The Cape Sundew gets nutrients it needs to survive from this relationship
The Fruit Fly
The Fruit Fly doesn't get anything from this relationship, only death.
