SPECIES
A Species is a group of organisms which can be INTERBREED to produce FERTILE OFFSPRING.
1 of 8
Asexual Reproduction
Bacteria reproducing asexually. An organism reproduces by making a copy of itself. There is no interbreeding with another organism so they don't fit the definition of species.
2 of 8
Hybrids
If you interbreed a male from one species with a female from a different species you'll get a hybrid. EXAMPLE: mule is a cross between a donkey and a horse. But hybrids are usually infertile so they aren't new species- this is difficult to classify
3 of 8
Evolution is a Continuous Process
Organisms change and evolve over time, so the way they've been classified might also have to change. sometimes a group of organisms will change so much it will form a new species- but it can be difficult to tell when this has happened.
4 of 8
Parasitic
Parasites live off hosts. They take what they need to survive, without giving anything back. This is a win-lose situation. EXAMPLE: Tapeworms absorb lots of nutrients from the host, causing them to suffer from malnutrition.
5 of 8
Mutualistic
Mutualism is a relationship where both organisms benefit. So it's a win-win relationship. EXAMPLE: Oxpeckers live on back of Buffalo.
6 of 8
Specialists
Specialists are organisms which are highly-adapted to survive in a SPECIFIC HABITAT. EXAMPLE: giant pandas are adapted to eat just bamboo.
7 of 8
Generalists
Generalists are organisms that are adapted to survive in a RANGE OF DIFFERENT HABITATS. EXAMPLE: black rats are able to survive in forests, cities and in areas of farmland.
