AQA Enviro Conservation part1

Definition of biomimetics

• The study of movement of biological molecules so the knowledge gained can enhance human transport.

• The study of living organisms so the knowledge gained can be applied to engineering or other technological developments.

• The study of diets in other organisms so that better nutrition can be developed in humans

• The study of wavelengths of energy and how UV can have an affect on humans

What are Crop Wild Relative Species (CWR)?

• CWRs have low biodiversity and are distantly related to domesticated crops.

• CWRs have poor quality nutrition but high biodiversity so can be cross bred with domesticated crops.

• CWR are wild plant varieties or species that are closely related to domesticated crops. CWRs may contain genetic characteristics that can be used in crop breeding programmes.

• CWR are wild plant varieties or species that are distantly related to domesticated crops. CWRs may are hard to hybridise with current domesticated crops.

What are Vavilov centres?

• Buildings around the world that contain rare species of plants and animals.

• Low biodiversity areas with rare species found nowhere else in the world.

• A treaty for the conservation of rare breeds of crop wild relative species.

• An area of the world, identified by high biodiversity, where crop plants were first domesticated and where wild varieties are still found.

What are the main issues of a species having a small gene pool? Select two.

• Higher chance of inbreeding

• More likely to pass on harmful recessive allele

• They have a greater chance of survival against environmental change.

• They have a large amount of genetic diversity .

What is meant by the term Ecosystem

• The place where an organism, species or population lives.

• A large geographical region with particular climatic features, in which a characteristic, unique community of species lives

• The role that an organism plays in its habitat, including its use of resources and its inter-relationships with other species.

• The community of organisms living in an area, their inter-relationships and interactions with their abiotic environment.
