question:How does biodiversity contribute to food security?
answer:Biodiversity plays a crucial role in ensuring food security for humans. Here's how: 1. Pollination: Many plant species rely on insects, such as bees and butterflies, for pollination. These insects transfer pollen from one flower to another, enabling fertilization and the production of seeds and fruits. Without pollinators, many crops would not be able to reproduce, leading to reduced food production. 2. Water Filtration: Wetlands, rich in biodiversity, act as natural water filters. They absorb pollutants and excess nutrients from water sources, purifying the water and making it safe for drinking, irrigation, and aquatic life. Clean water is essential for crop growth and human health. 3. Soil Fertility: The soil beneath our feet is teeming with billions of microorganisms, including bacteria, fungi, and earthworms. These organisms break down organic matter, release nutrients, and improve soil structure, making it more fertile for crop production. Soil biodiversity is crucial for sustainable agriculture. 4. Crop Diversity: Biodiversity provides us with a wide variety of crops to choose from. Different crops have different nutritional profiles, and consuming a diverse range of fruits, vegetables, and grains ensures that we meet our vitamin and mineral needs for optimal health. Crop diversity also helps reduce the risk of crop failure due to pests or diseases.

question:Lavage Rapide, a Canadian company, owns and operates a large automatic car wash facility near Montreal. The table below shows data about the company's costs. | Fixed Cost per Month | Cost per Car Washed | |---|---| | Cleaning supplies | 0.80 | | Electricity | 1,200 | 0.15 | | Maintenance | 0.20 | | Wages and salaries | 5,000 | 0.30 | | Depreciation | 6,000 | | Rent | 8,000 | | Administrative expenses | 4,000 | 0.10 | For example, electricity costs 1,200 per month plus 0.15 per car washed. The company expects to wash 9,000 cars in August and to collect an average of 4.90 per car washed. Required: Prepare Lavage Rapide's planning budget for August.
answer:The planning budget for August is prepared by multiplying the cost per car washed by the number of cars expected to be washed and adding the fixed costs. The sales figure is calculated by multiplying the number of cars expected to be washed by the average price per car wash. The income figure is calculated by subtracting the total expenses from the sales figure. Lavage Rapide Planning Budget for August | Item | Formula | Amount | |---|---|---| | Sales | 9,000 cars × 4.90 per car | 44,100 | | Cleaning supplies | 9,000 cars × 0.80 per car | 7,200 | | Electricity | 1,200 monthly fixed cost + (9,000 cars × 0.15 per car) | 2,550 | | Maintenance | 9,000 cars × 0.20 per car | 1,800 | | Wages and salaries | 5,000 monthly fixed cost + (9,000 cars × 0.30 per car) | 7,700 | | Depreciation | N/A | 6,000 | | Rent | N/A | 8,000 | | Administrative expenses | 4,000 monthly fixed cost + (9,000 cars × 0.10 per car) | 4,900 | | Total expenses | N/A | 38,150 | | Income | Sales - Total expenses | 5,950 |
