The document provides an overview of key concepts in terrestrial ecology, including:
- Ecology is the study of interactions between organisms and their environment.
- Ecosystems consist of biotic (living) and abiotic (non-living) components that interact.
- Energy flows through ecosystems via food chains and webs, with only 10% being transferred between trophic levels.
- Human activities have impacted carbon, nitrogen, phosphorus and sulfur cycles, altering global ecosystems.
- Climate and precipitation determine biome types such as deserts, forests, grasslands and tundra across the planet.
Basic vocabulary and organization of ecology. This is for a high school environmental science class. Information is from the book
Environmental Science: toward a sustainable future 11th edition.
ecosystem topic will help you in understanding the basic means and other components like structure, functions, types, ecological pyramid, energy flow in ecosystem and many more environment related studies.
Ecosystems are distinguished by a combination of biotic and abiotic factors. The slideshow first shows images of each terrestrial ecosystem separated by climate zone, and then finishes with mystery ecosystems for students to identify and describe. Ask your students to identify the abiotic factors such as amount of precipitation, elevation, temperature, etc., and how that affects the life zone of of the ecosystem (biodiversity, height of plant growth, etc.).

MAJOR TYPES OF ECOSYSTEMS
1. TERRESTRIAL ECOSYSTEMS
2. AQUATIC ECOSYSTEMS
Terrestrial ecosystems
A terrestrial ecosystem is an ecosystem found only on landforms.
Six primary terrestrial ecosystems exist:
tundra,
taiga,
temperate deciduous forest,
tropical rain forest,
grassland; and
desert.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Editor's Notes
Figure 3.2 Natural capital: levels of organization of matter in nature. Ecology focuses on five of these levels.
Figure 3.11 Natural capital: range of tolerance for a population of organisms, such as fish, to an abiotic environmental factor—in this case, temperature. These restrictions keep particular species from taking over an ecosystem by keeping their population size in check.
Figure 3.14 Natural capital: the main structural components of an ecosystem (energy, chemicals, and organisms). Matter recycling and the flow of energy—first from the sun, then through organisms, and finally into the environment as low-quality heat—links these components.
Figure 3.17 Natural capital: a food chain. The arrows show how chemical energy in food flows through various trophic levels in energy transfers; most of the energy is degraded to heat, in accordance with the second law of thermodynamics.
Figure 7.9 Natural capital: examples of mutualism. (a) Oxpeckers (or tickbirds) feed on parasitic ticks that infest large, thick-skinned animals such as the endangered black rhinoceros. (b) A clownfish gains protection and food by living among deadly stinging sea anemones and helps protect the anemones from some of their predators. (c) Beneficial effects of mycorrhizal fungi attached to roots of juniper seedlings on plant growth compared to (d) growth of such seedlings in sterilized soil without mycorrhizal fungi.
Figure 3.7 Natural capital: life on the earth depends on the flow of energy (wavy arrows) from the sun through the biosphere and back into space, the cycling of crucial elements (solid arrows around ovals), and gravity , which keeps atmospheric gases from escaping into space and helps recycle nutrients through air, water, soil, and organisms. This simplified model depicts only a few of the many cycling elements.

Figure 5.27 Natural capital degradation: major human impacts on the world’s grasslands. Some 70% of Brazil’s tropical savanna—once the size of the Amazon—has been cleared and converted to the world’s biggest grain growing area.
