Discuss your opinions and attitude towards biodiversity and the health of ecosystems. Is biodiversity something that your personally value? Do you appreciate the benefits that biodiversity offers to humans, or is it something that you care little about? Do you wish that more people shared your perspective?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. ... Healthy ecosystems can better withstand and recover from a variety of disasters.

What is biodiversity Why is biodiversity important for human life?

Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services. Note: Species are found 3 million to 100 million on earth

Why is it important to maintain biodiversity in every ecosystem?

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. ... Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.

What are 5 benefits of biodiversity?

Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection. Provide for nutrient storage and recycling.

What is the importance of biodiversity?

Biodiversity supports ecosystems to provide and purify water. Every two minutes a child dies from a water-borne disease. But through the continuous recycling of water, biodiversity maintains ecosystem services needed to sustain drinking water supplies. Ecosystems also play a significant role in purifying water

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.

the product of the pressure and volume is also constant
