Environmental Science Concepts Segment 1

Front

Environmental Science

Back

The study of impacts of human activities on environmental systems, including large scale actions like clearing land, fishing, and mining, as well as small actions like driving, turning on lights, and using plastic.

Front

Environment

Back

The sum of total conditions, including living and nonliving factors around an organism. It includes food sources, predators, and can range from small ponds to large mountain ranges.

Front

Interdisciplinary in Environmental Science

Back

It covers aspects of biology, earth, and atmospheric sciences, as well as fundamental principles of chemistry, physics, human population dynamics, biological and natural resources.

Front

System in Environmental Science

Back

A set of living and/or nonliving things that can usually be isolated. It is important for understanding the environment and is connected to studying the environment.

Front

Biological diversity includes diversity of genes, species, and habitats.

Back

Diversity of genes, species, habitats ecosystems

Front

Species are distinct groups of organisms.

Back

Species group of organisms distinct from other groups in morphology, physiology, biochemical properties can produce viable offspring

Front

Loss of keystone species affects entire ecosystems.

Back

Loss of keystone species cause harm/loss to entire ecosystem

Front

Worldwide grain production is a result of:

Back

- Soils - Climate conditions - Land area under cultivation - Human labor - Energy - Water expanding on growing food

Front

Agricultural practices range from:

Back

- High-intensity monoculture (one crop) - Low-intensity polyculture (many crops)

Front

High-intensity practices can lead to:

Back

- Soil erosion - Runoff of fertilizers and animal waste into waterways - Buildup of pesticides - Decreased land quality
