(c)range of ecosystems on earth
what is meant by the direct and indirect values of biodiversity?
direct: the benefits which are obtained from the products of biodiversity

Which of the following is not a reason to maintain biodiversity?
A Many plant species are a possible source of medicines.
B Biodiversity provides inspiration to writers and poets.
C High biodiversity helps to keep biochemical cycles in balance.
D Increasing human populations require more land for agriculture.
D Increasing human populations require more land for agriculture.
the definition of natural products is
any materials produced by living organisms such as plants or microorganisms. for example wood or silk
3 benefits of the proper maintenance of biodiversity to tourism are
(2)improves employee productivity
(3)attracts investment and support from socially responsible investors

name two examples of how tourism may contribute to biodiversity loss
(1)poorly managed scuba diving activities may cause damage to coral reefs
(2)the clearing of land in order to provide space develop hotels etc.
(1) the idea that humans have custody of the earth and therefore must protect the organisms that live here with us
(2)the concept that other organisms have an equal right to exist on the Earth with us.

Discuss why biodiversity loss is a major concern. In your discussion, TWO indirect benefits of maintaining biodiversity.
Two indirect benefits: (1)absorption of CO2 from the atmosphere by plants , (2)pollination of flowers by bees, (3)transpiration of plants, contributing to the water cycle
Give an example and explain why medicine is important in biodiversity.
Biodiversity provides important resources for medical research -
Examples of species of interest to medical science includes bears (for insights into osteoporosis, cardio-vascular disorders, renal disease and diabetes), sharks
(osmoregulation and immunology),etc.
When ecosystems are intact, biological processes are preserved. These processes include: (5)
Nutrient and water cycling, harvesting light through photosynthesis, energy flow through the food web, and patterns of plant succession over time.
Give two examples of how Biodiversity has affected Tourism in the Caribbean
Tourist destinations such as tropical forests, beaches, national parks and even urban areas depend on their natural beauty to attract visitors and enchant them during their stay.
- Black River Safari in Jamaica attracts tourists from all over the world to experience the diversity of organisms in the river and surrounding areas, such as, the crocodiles and water lilies.
