Mengenal Biosfer dan Faktor Persebaran Flora dan Fauna | Geografi Kelas 11 | EDURAYA MENGAJAR

Summary

This video explains the factors influencing the distribution of flora and fauna across the Earth. It explores the biosphere—where life exists—and how elements like air temperature, humidity, wind, rainfall, soil composition, and the shape of the Earth's surface (physiographic factors) play a role in determining where different species thrive. The script highlights how animals like penguins survive in cold climates while camels prefer hot ones, and discusses how plants and animals interact with their environment to survive. The video also touches on biotic factors, showing how living organisms contribute to these environmental dynamics.

Takeaways

• 😀 Penguins live in cold temperatures, but they don't naturally live in the North Pole. Their distribution is influenced by various factors.
• 🌍 The biosphere is the layer of Earth that supports life, including humans, animals, and plants. It consists of the atmosphere, water, and soil.
• 💡 Flora and fauna thrive in different biosphere zones based on their specific needs and abilities to survive.
• 🌡️ Climate factors such as temperature, humidity, wind, and rainfall significantly affect the distribution of plants and animals.
• 🌱 Soil characteristics, including humus, nutrients, and water content, are vital for the growth of plants and affect where flora can grow.
• 🐾 Animals choose habitats based on food needs, with some acting as predators of plants and others choosing locations that suit their survival requirements.
• 🏞️ Physiographic factors, like the shape of the Earth's surface, also influence the distribution of life, as seen in tea plantations that are found in highland areas.
• 🌧️ The presence of water, air, and the proper soil conditions are critical for the survival of both plants and animals.
• 🌍 Different climates and landscapes create specific ecosystems, such as cold environments for penguins and hot deserts for camels.
• 🌿 Biotic factors, such as worms in the soil, play a role in maintaining soil fertility, which in turn supports plant life and influences where flora and fauna can live.

Q & A

Why can penguins survive in cold temperatures like the North Pole?

Penguins are adapted to cold climates due to their physical characteristics, such as thick layers of fat and feathers that provide insulation, and their ability to regulate body temperature effectively.

Why don’t penguins live in dry areas?

Penguins thrive in cold, coastal environments where they can access food such as fish, which is abundant in cold water. Dry areas do not offer the necessary food sources or environmental conditions for penguins to survive.

What is the biosphere?

The biosphere refers to the layer of Earth that supports life, including all living organisms and the environments in which they exist, such as land, water, and air.

What are the factors that influence the distribution of flora and fauna?

The distribution of flora and fauna is influenced by various factors, including climatic factors (temperature, humidity, wind, rainfall), edaphic factors (soil conditions), physiographic factors (terrain and landforms), and biotic factors (interaction with other living organisms).

How does climate affect the distribution of flora and fauna?

Climate factors, such as temperature, humidity, wind, and rainfall, play a critical role in determining where specific species can thrive. For example, animals and plants have adapted to specific temperature ranges and moisture levels that suit their survival needs.

What role does soil play in the distribution of plants?

Soil is crucial for plant growth as it provides essential nutrients, water, and air. Plants will grow in soil that meets their needs for humus, nutrients, water content, and air availability. Different types of soil support different types of flora.

What are edaphic factors?

Edaphic factors are those related to the soil, including its composition, structure, nutrient content, and moisture levels, which significantly influence plant growth and the types of flora that can live in a particular area.

Why can certain animals, like camels and donkeys, live in hot environments?

Animals like camels and donkeys have adapted to survive in hot climates by developing specialized features, such as the ability to store water, regulate body temperature, and withstand extreme conditions like intense heat and dryness.

What are physiographic factors, and how do they affect living organisms?

Physiographic factors refer to the physical features of the Earth's surface, such as elevation, terrain, and landforms. These factors can impact the availability of resources like water and food, as well as influence temperature and climate, affecting the types of flora and fauna that can survive in an area.

How do biotic factors affect the distribution of flora and fauna?

Biotic factors are the interactions between living organisms, such as predation, competition, and symbiosis. These interactions can influence the distribution of species, as animals and plants may either thrive or struggle depending on the presence of other organisms and their ecological relationships.
