Chapter 4: Population and Community (Environmental Science)

1. Describe how human actions, such as removing a predator or bringing in a new species, can impact other species in an ecosystem.

2. In describing populations, where do the r and k come from? What do they stand for? Explain how these strategies differ, using examples.

Chapter 5: Ecosystems: Energy, Patterns and Disturbance (Environmental Science)

1. Create a diagram of a typical food web, labeling each of the different components.

2. Identify and describe the biotic and abiotic factors in the biome in which you live.

Chapter 6: Wild Species and Biodiversity (Environmental Science)

1. How does

Explanation / Answer

Chapter 4

By the human action if a predator or prey is affected than it results in ecological imbalance. For example, eradication of predator increases prey concentration in the nature while eradication of prey decreases predator concentration.

R comes from rate while k comes from capacity. The letter K stands for “Kapazitatsgrenze”. The r-selection differs from k-selection because r depends on high growth rate while, k depends on carrying capacity.

In r-selection the parent has capacity to produce high number of off-springs but very few reach to adult stage. For example, mice produce many offspring.

In k-selection the parent has capacity to produce less number of off-springs but there is high probability to reach their adult stage. For example, humans produce one or two offspring.

The fundamental classification of biome is terrestrial and aquatic biomes.

Humans are living in terrestrial biome where biotic factors include all living organisms (humans, animals, microbes etc.) and abiotic factors include environment (temperature) that surrounds and affects living organisms.

Chapter 6

Instrumental value depicts that the value if it is good and provides the mean for acquiring something else of value. For example, maintenance of biodiversity.

Intrinsic value depicts that the value if it is good “in and of itself” without acquiring something else. For example, catching of prey by the predator is a benefit only for predator.

Chapter 7

Ecosystem capital is the resources that are obtained from nature for the survival and economic benefit of humans.

For example, minerals, agriculture, fisheries etc.

It is an economic theory proposed by Garret Hardin. This theory states that individuals acting independently and rationally according to each self’s interest behave contrary to best interests of whole group by depleting some common resource.

For example, failing fisheries- every year catching of fishes is being increased which, in turn results in reduction of fish population in the oceans. Ocean is a common resource where people are acting independently and rationally to catch fishes.

Chapter 1

World views are a framework of reality and make sense of life and the world. It is an ideology, philosophy, theology, movement or religion that provides an approach to understand God, world, and man’s relation to God and world.

According to bible, the primary reason for humans to exist on earth is to love and serve God which brought a remarkable change in people’s behaviour.

Chapter 2

According to above picture, nature was perceived as raw material and it was the product of God’s creation. Nature was God’s instrument to affect humankind and had no independent power to effect change. Humans could affect the natural world by acting as God’s representatives they could utilize nature’s resources for their own purposes. The natural world was subject to both divine and human control.

Humans are distinct from nature and are perceived as different kind in nature, though they are created along with the rest of the natural world. This distinction is due to culture and their ability to create their own, artificial environment that is superimposed on the natural world.
