Important Questions for Class 10 Science Chapter 15 - Our Environment

Question 1

What is an ecosystem, and what are its components?

Answer

Imagine an ecosystem as a big, bustling community where living things (like plants and animals) and non-living things (such as soil and air) hang out together. It's like a happening neighborhood where everyone, living or not, plays a role in keeping things running smoothly.

Question 2

Explain the concept of food chains.

Answer

Think of a food chain like a menu for nature. It starts with plants, the chefs of the kitchen, who make their food through photosynthesis. Then, animals come in to eat the plants, and other animals follow, creating a chain of who eats whom.

Question 3

How do food webs differ from food chains?

Answer

Picture a food web as a massive dinner party with lots of interconnected tables. Unlike a food chain, it shows the complicated relationships among different organisms. It's like saying, "Hey, in nature, everyone is connected in more ways than we realize!"

Question 4

What are the consequences of disrupting a food chain in an ecosystem?

Answer

Messing with a food chain is like pulling a Jenga block – the whole tower could fall! If you remove one player, like a predator or prey, it creates a domino effect, messing up the balance of who eats whom and causing chaos in the ecosystem.

Question 5

How do human activities impact the environment?

Answer

We humans are a big deal! Our actions, like chopping down trees and spewing out pollution, mess with the environment. It's like throwing a party in nature's house and leaving a huge mess behind. We need to be careful guests!

Question 6

Explain the greenhouse effect and its role in climate change.

Answer

Think of Earth as a cozy blanket. The greenhouse effect is like adding an extra layer – it keeps us warm. But when we humans release too many gases (like carbon dioxide), it's like wrapping ourselves in a super thick blanket, making the Earth too warm, and that's not good.

Question 7

What is the ozone layer, and why is it important?

Answer

The ozone layer is like Earth's superhero shield, protecting us from harmful UV rays. It's our very own sunscreen. Without it, we'd be at risk of sunburns, just like Earth forgetting to put on sunscreen!

Question 8

Explain how human activities contribute to ozone layer depletion.

Answer

Imagine humans as accidental villains, releasing harmful stuff like CFCs. These substances are like tiny wrecking balls, breaking down the ozone shield. We need to stop being unintentional troublemakers!

Question 9

What are the consequences of ozone layer depletion?

Answer

Ozone depletion is like leaving the front door wide open for UV rays. It can harm our skin, mess with the ocean's balance, and even mess up our crops. It's like Earth losing its protective shield, and we need to fix that.

Question 10

How can we prevent further depletion of the ozone layer?

Answer

It's time for us to be Earth's superhero sidekicks! We can stop using harmful substances like CFCs and support global agreements (like the Montreal Protocol) that aim to put an end to these bad guys.

Question 11

Explain the concept of acid rain and its impact on the environment.

Answer

Acid rain is like nature's sour surprise. When pollutants from burning fossil fuels mix with rain, it becomes acidic. This acidic rain harms soil, water, and plants, disrupting ecosystems and even damaging buildings and statues over time.

Question 12

What are the dangers of plastic pollution in marine environments?

Answer

Picture the ocean as a giant bathtub, and plastic pollution as the dirty water. Marine animals mistake plastic for food, leading to ingestion and entanglement. It's like filling their homes with harmful trash, disrupting the delicate balance of marine life.

Question 13

How does overfishing impact marine ecosystems?

Answer

Overfishing is like taking too many snacks from the fridge without restocking. It depletes fish populations, disrupts the food chain, and can even lead to the collapse of entire ecosystems. We need to fish responsibly to maintain a healthy balance.

Question 14

Explain the role of the ozone layer in protecting life on Earth.

Answer

The ozone layer acts like Earth's sunglasses, blocking harmful UV rays. Without this protective shield, we'd be exposed to intense sunlight, leading to skin cancers, cataracts, and harm to both plants and animals. It's our natural sunscreen.

Question 15

How does the use of chemical fertilizers and pesticides affect the environment?

Answer

Chemical fertilizers and pesticides are like strong medicine for plants. While they help crops grow, they can also harm the soil, water, and even non-target organisms. It's a balancing act between boosting agriculture and protecting the environment.

Question 16

Explain the importance of the ozone layer in preventing climate change.

Answer

The ozone layer and climate change are like two different superheroes. The ozone layer shields us from harmful UV rays, while climate change deals with global temperature regulation. Protecting both is crucial for maintaining a healthy and stable environment.

Question 17

How can individuals contribute to reducing air pollution in urban areas?

Answer

Individuals can be air quality superheroes by using public transport, reducing car emissions, and supporting cleaner energy sources. It's like each person holding a tiny broom, sweeping away the dust to keep the air fresh and clean

Question 18

Explain the concept of eutrophication and its impact on aquatic ecosystems.

Answer

Eutrophication is like overfeeding a pond. Excessive nutrients, often from agricultural runoff, lead to algae overgrowth. When these algae die, they consume oxygen during decomposition, harming aquatic life and creating "dead zones."

Question 19

How does the loss of biodiversity affect the stability of ecosystems?

Answer

Biodiversity is like a safety net for ecosystems. The more diverse, the more resilient. Losing species is like removing threads from a safety net – it weakens the structure and makes the entire ecosystem more vulnerable to disturbances.

Question 20

Explain the concept of renewable and non-renewable resources.

Answer

Imagine resources as snacks. Renewable resources, like solar and wind energy, are like snacks that keep getting restocked. Non-renewable resources, like fossil fuels, are like a limited bag of chips – once they're gone, they're gone. Balancing both ensures a sustainable snack shelf for the future.
