Life Forms and Their Environment

Apa itu ekosistem?

• Sebuah spesies hewan tunggal di suatu habitat

• Sebuah pola cuaca

• Sekumpulan tanaman di taman

• Sebuah ekosistem adalah komunitas organisme hidup dan lingkungan fisiknya yang berinteraksi sebagai suatu sistem.

Describe the interaction between producers and consumers.

• Consumers create goods and services for producers.

• Producers supply goods and services to consumers, who demand and purchase them, creating a dynamic market interaction.

• Consumers supply goods and services to producers.

• Producers and consumers have no interaction in the market.

What role do decomposers play in an ecosystem?

• Decomposers produce energy for plants.

• Decomposers compete with plants for sunlight.

• Decomposers recycle nutrients and help maintain ecosystem balance.

• Decomposers are primary consumers in the food chain.

Explain the difference between a food chain and a food web.

• A food chain includes multiple species, while a food web includes only one species.

• A food chain is a complex network, while a food web is a simple sequence.

• A food chain shows only herbivores, while a food web shows only carnivores.

• A food chain is a linear sequence of energy transfer, while a food web is a complex network of interconnected food chains.

What is a biome? Give two examples.

• Wetland and Steppe

• Desert and Rainforest

• Savanna and Grassland

• Ocean and Tundra

How do habitats differ from biomes?

• Biomes are specific environments for organisms.

• Habitats and biomes are the same thing.

• Habitats are specific environments for organisms, while biomes are larger ecological areas defined by climate and geography.

• Habitats are larger areas than biomes.

What adaptations help animals survive in deserts?

• Hibernation during summer months

• High metabolic rate for energy production

• Brightly colored fur for camouflage

• Adaptations include water conservation, nocturnal behavior, reflective body coverings, and efficient thermoregulation.

Why is biodiversity important for ecosystems?

• Biodiversity is irrelevant to ecological processes.

• Biodiversity is important for ecosystems because it increases resilience, productivity, and stability, enabling them to better adapt to changes and support essential ecological processes.

• Biodiversity decreases ecosystem productivity and stability.

• Biodiversity only benefits human activities, not ecosystems.

What are some human activities that threaten biodiversity?

• Sustainable farming practices

• Wildlife conservation efforts

• Renewable energy development

• Deforestation, pollution, overfishing, habitat destruction, climate change.

How does pollution affect aquatic life?

• Pollution improves water clarity for aquatic organisms.

• Pollution enhances aquatic life by providing nutrients.

• Pollution negatively impacts aquatic life by introducing toxins, depleting oxygen, and disrupting ecosystems.

• Pollution has no effect on aquatic life.
