15. Homework 1. Outline and complete: Concept check 1.2
2. Kingdom Exploration Pre-Lab
Dining in the trees. Shown is a female leopard and her daughter who have just killed a duiker (a small antelope). They could eat right after killing it, but then it might get stolen. Better for the mother to haul the prey up into a tree where it can be consumed without worry that a lion or hyena will steal it.
If you compare a leopard to another big cat that lives in the same area in Africa, the lion. you’ll see there are important differences. Leopards are nocturnal, whereas lions are diurnal. Leopards eat a much greater variety of prey than lions. Leopards are physically much smaller than lions only about 1/3 their size, but leopards are faster.
Compared to lions, leopards are solitary animals, maintaining separate non-overlapping territories. They don’t compete with each other for prey. Sensitive whiskers on its face help the cat navigate through dense veg while hunting at night. Spots provide camouflage in dry grasses of African plains, but they are also found in deserts, hill country and jungles.

16. Concept 1.2 Biology explores life in its diverse forms

17. Objectives 1. Use the term species in discussing life’s diversity.
2. Explain the basic strategy biologists use in classifying organisms.

31. Energy and life
                                                                                                                                                                                                    
Figure 1-15 Energy enters an ecosystem as sunlight. Plants are producers that convert light energy to chemical energy stored in food. Animals and other consumers obtain their energy in chemical form by eating. Energy exits an ecosystem as heat, which all organisms generate as they perform work. 31

32. Regulation 32

33. Adaptation and Evolution
