Worms are very good at breaking down natural materials and turning them into compost. They have a unique digestive system that allows them to consume organic waste, such as leaves and food scraps, and convert it into nutrient-rich compost through their excrement. This process, known as vermicomposting, helps to break down organic matter faster and enrich the soil with beneficial nutrients. Worms play a crucial role in maintaining the balance of ecosystems by recycling organic waste and contributing to the fertility of the soil.

The correct answer is "are harmful to the environment." This is because landfill sites are locations where waste materials are disposed of, and the decomposition of these materials can release harmful pollutants and gases into the environment. These pollutants can contaminate the soil, water, and air, leading to various negative impacts on ecosystems and human health. Therefore, landfill sites are generally considered to be detrimental to the environment.

They are not mammals because they do not have fur or produce milk. They are not amphibians because they do not have moist, permeable skin or undergo metamorphosis. Therefore, the correct answer is that a crocodile is a reptile.

Apple cores are the correct thing to put into a compost bin because they are organic waste that can be easily broken down and decomposed. Composting involves the natural process of decomposition, and apple cores provide valuable nutrients and organic matter to the compost. They also help to maintain the balance of carbon and nitrogen in the compost, which is necessary for the breakdown of organic materials. Additionally, apple cores are biodegradable and do not contain any harmful chemicals or toxins that could negatively impact the composting process.

Leaving an old fridge by the side of the road would not be a good way to dispose of it because it can pose environmental and safety hazards. Abandoning it in this manner can lead to the release of harmful refrigerants and chemicals into the environment, contributing to pollution. Additionally, it can create a potential safety hazard for pedestrians and drivers. It is important to properly dispose of old fridges through appropriate channels such as recycling centers or scrap metal collection services that can handle the disposal and recycling process safely and responsibly.

The phrase "Reduce, reuse, recycle" is used to emphasize the importance of minimizing waste that goes into landfills. By reducing the consumption of resources, reusing items instead of throwing them away, and recycling materials whenever possible, we can effectively reduce the amount of waste that ends up in landfills, thereby minimizing environmental impact and promoting sustainability.

This paper is made from elephant poo. Elephant dung is collected and processed to create a pulp, which is then used to make paper. This process is an eco-friendly alternative to cutting down trees for paper production.

Energy saving light bulbs use a fifth of the energy of normal bulbs. This means that they are designed to be more efficient and consume less energy while still producing the same amount of light. By using only a fifth of the energy, these bulbs help to reduce electricity consumption and lower energy costs, making them a more environmentally friendly and cost-effective option.

Hummingbirds produce a humming sound due to the rapid flapping of their wings. They have the ability to beat their wings at an incredibly high speed, ranging from 50 to 200 times per second, depending on the species. This rapid movement creates vibrations in the air, resulting in the characteristic humming noise. The humming sound is essential for communication and courtship rituals among hummingbirds, as well as for territorial defense.

The logo represents a blue and green symbol with a person in the center, which signifies the organization's commitment to social and environmental sustainability.

The most common type of natural disaster is a flood. Floods occur when there is an overflow of water onto normally dry land, often caused by heavy rainfall, melting snow, or dam failure. Floods can cause significant damage to infrastructure, homes, and crops, and can result in loss of life. They are a common occurrence worldwide and can happen in both coastal and inland areas.

Forests play a crucial role in regulating the global climate by absorbing carbon dioxide from the atmosphere. Deforestation, the clearing of forests for other land uses, reduces the planet's capacity to absorb carbon dioxide, contributing to the greenhouse effect and climate change.

Habitat loss is the biggest threat to animal populations worldwide because it disrupts their natural environment and leads to the destruction or fragmentation of their habitats. This loss of habitat results in a decrease in available resources, such as food and shelter, which affects the survival and reproduction of animal species. It also forces animals into closer proximity with human settlements, increasing the chances of conflicts and human-wildlife interactions. Additionally, habitat loss can lead to the loss of biodiversity and the extinction of species, further disrupting ecosystems and the balance of nature.

The Toyota Prius is a hybrid model that uses both electricity and petrol for power. It is known for its fuel efficiency and low emissions, making it a popular choice among environmentally conscious drivers.
