Interaksi Makhluk Hidup dengan Lingkungan - Komponen Biotik dan Abiotik | Materi IPA Kelas7

Summary

In this lesson, students are introduced to Chapter 2, focusing on the interaction of living things with their environment. The concept of 'environment' is explored, highlighting both biotic (living) and abiotic (non-living) components. The lesson explains how these components interact within ecosystems, with examples such as deer, fish, and plants. It also emphasizes the importance of habitats and the dynamic relationships between organisms and their surroundings. The session concludes with a preview of upcoming lessons on food webs and chains.

Takeaways

• 😀 The environment is the physical, chemical, and biotic condition surrounding an organism.
• 😀 The environment is a dynamic and complex system where various components affect one another.
• 😀 Environmental quality can change, either improving or worsening, due to the influence of living organisms.
• 😀 The environment consists of two main components: biotic (living things) and abiotic (non-living things).
• 😀 Biotic components include humans, animals, plants, and microorganisms like bacteria, fungi, yeast, protozoa, and viruses.
• 😀 Abiotic components include inanimate objects such as water, soil, air, and light.
• 😀 A habitat is a place where a living organism resides, consisting of both biotic and abiotic components.
• 😀 In a habitat, there are interactions between living things (biotic) and non-living things (abiotic).
• 😀 Example interactions include a deer breathing oxygen from the air (abiotic) and fish interacting with water (abiotic).
• 😀 Living organisms also interact with each other, such as deer eating grass (biotic interaction).
• 😀 The next topic in the course will explore food webs and food chains, continuing the discussion on interactions in ecosystems.

Q & A

What is the definition of the environment according to the script?

The environment is everything outside the individual, including physical, chemical, and biotic conditions, which form a complex system that can affect one another.

What are the two main components of the environment?

The two main components of the environment are the biotic components (living things like humans, animals, plants, and microorganisms) and abiotic components (non-living things like water, soil, air, and light).

What are microorganisms, and can you provide some examples?

Microorganisms, also known as microbes, are tiny living things that consist of one or several collections of cells. Examples include bacteria, fungi, yeast, protozoa, and viruses.

What is a habitat, and why is it important?

A habitat is a place where living things reside. It provides the necessary conditions for survival and interaction between biotic and abiotic components of the ecosystem.

Can you give an example of how living things interact with non-living things?

For instance, a deer breathes oxygen from the air, which is an abiotic component. The deer, a biotic component, interacts with the air, a non-living thing.

How do biotic components and abiotic components interact in an ecosystem?

Biotic components, like animals and plants, interact with abiotic components, such as water and air, to survive. For example, fish live in water and depend on it for their habitat, while plants rely on sunlight for photosynthesis.

What is the role of the deer in the given ecosystem example?

The deer in the ecosystem is a herbivore that interacts with the biotic component of grass or plants. The deer eats the plants, thus engaging in a biotic-to-biotic interaction.

What does it mean that the environment is dynamic?

The environment is dynamic because its conditions are constantly changing, influenced by interactions among biotic and abiotic components, as well as external factors.

What could cause the environment to change for the worse?

Environmental changes for the worse can be caused by human activities or natural factors that disrupt the balance between biotic and abiotic components, leading to negative effects like pollution or habitat destruction.

What will the next lesson cover after the topic of interactions in the environment?

The next lesson will cover food webs and food chains, building on the understanding of how living things interact with each other and their environment.
