Plant Ecology and Environmental Factors

The video introduces grade seven students to ecology, focusing on how living things interact with their environment. It covers the components of ecosystems, including biotic and abiotic factors, and explores climatic factors like light and temperature. The role of water and wind in ecosystems is discussed, along with edaphic and physiographic factors such as soil and topography. The lesson concludes with a summary and resources for further learning.

What is the primary focus of ecology?

• The study of non-living things

• The study of interactions between living organisms and their environment

• The study of human-made environments

• The study of celestial bodies

Which of the following is NOT a climatic factor?

• Temperature

• Soil pH

• Wind

What process do plants use to convert carbon dioxide into energy?

• Evaporation

• Respiration

• Photosynthesis

• Decomposition

Which type of plant requires long periods of darkness to flower?

• Day-neutral plants

• Long-day plants

• Hydrophytes

• Short-day plants

What is the main component of living cells?

• Water

• Oxygen

• Nitrogen

• Carbon

Which type of plant thrives in dry habitats?

• Heliophytes

• Xerophytes

• Hydrophytes

• Mesophytes

What is the role of soil pH in an ecosystem?

• It affects the availability of nutrients for plant growth

• It determines the amount of sunlight plants receive

• It influences the wind patterns

• It controls the temperature of the environment

What does topography refer to?

• The temperature variations in an ecosystem

• The amount of rainfall in an area

• The physical features of the land surface

• The chemical composition of soil

How does altitude affect vegetation?

• Higher altitudes have more diverse plant species

• Altitude has no effect on vegetation

• Lower altitudes have stunted plant growth

• Mid altitudes experience more stunted growth
