GCSE WJEC Biology Unit 2

The most familiar living things fall into two groups. What are these?

• Animals and plants

• Mammals and invertebrates

• Flowering and non-flowering

• Vertebrates and invertebrates

What is meant by vertebrates?

• Animals which have an inverted backbone

• Animals which have a backbone

• All species which have a backbone

• A unicellular organism

What are the classifications for plants?

• Fungi and non-fungi

• Flowering and non-flowering

• Moss and spiral

• White and/or green

Why do scientists classify living organisms?

• It makes it easier to identify organisms and allows scientists to communicate with each other

• To collect data about a specific organism and anything related to it

• For ensuring that every organism in the world is accounted for and that they are widely recognised in the scientific community

• For easiness

What are behavioural adaptations?

• Behavioural adaptations are the way the animal responds to its environment and displays its traits, e.g. wild-tempered

• They are the adaptations an animal has from its DNA that instills a certain behaviour pattern within them

• Behavioural adaptations could include the time of day when an animal is active or type of food it eats

• When an animal or plant reacts 'strangely' to its environment e.g. by unexpected movements

The needs of living organisms: What are they?

• Light, Food, Water, Oxygen, Carbon dioxide, minerals, competition, prey

• Light, Food, Water, Oxygen, Carbon dioxide, minerals, competition, prey, mate

• Sunlight, food, water, heat, oxygen

• Light, Food, Water, Oxygen, Carbon dioxide, minerals
