KEANEKARAGAMAN HAYATI- FAKTOR-FAKTOR YANG MEMPENGARUHI PERSEBARAN FLORA & FAUNA - GEOGRAFI KELAS XI
Summary
TLDRThe video explores the uneven distribution of flora and fauna across the Earth, emphasizing how population pressures, habitat changes, and various abiotic and biotic factors shape ecosystems. Key influences include climate conditions, soil quality, and topography, which determine species survival and adaptability. Human activities significantly impact habitats, leading to species endangerment, while interactions among organisms, such as pollination, are vital for plant reproduction. Understanding these dynamics is essential for effective conservation and management strategies, highlighting the need for preserving biodiversity and ecological balance.

Q & A
What factors influence the distribution of flora and fauna on Earth?
-The distribution is influenced by abiotic factors like climate, soil, and topography, as well as biotic factors such as human impact and interactions among species.
How does climate affect plant and animal species?
-Climate determines the types of plants and animals that can survive in an area, with cold-climate species having adaptations like thicker fur for warmth.
What role does soil play in the ecosystem?
-Soil characteristics, including acidity (pH), texture, and nutrient content, directly affect plant growth, which in turn impacts the animals that rely on these plants for food and habitat.
In what ways does topography impact biodiversity?
-Topography influences the types of habitats available, with factors such as slope and elevation affecting which species can thrive in certain areas.
What human activities threaten natural habitats?
-Activities such as agricultural expansion, deforestation, and urban development lead to habitat destruction, threatening various species with extinction.
What are some conservation strategies mentioned in the transcript?
-Conservation strategies include the establishment of protected areas, reforestation efforts, and regulations on hunting to protect endangered species.
How do animals contribute to the spread of plants?
-Animals, especially pollinators like bees and butterflies, assist in the reproduction of plants by transferring pollen from one flower to another, facilitating cross-pollination.
What adaptations do plants have in response to environmental conditions?
-Plants adapt through various means, such as shedding leaves in autumn to conserve water during cold months or developing thick leaves to survive in arid conditions.
What is the significance of understanding ecological factors?
-Understanding these factors is crucial for developing effective strategies for environmental management, conservation efforts, and maintaining biodiversity.
How do changes in habitat affect species survival?
-Changes in habitat can disrupt the ability of species to adapt, leading to declines in populations or local extinctions if they cannot find suitable environments.
