1. Introduction
1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
Tropical rainforests grow in nutrient-poor soil which is only two to three inches deep.
THEN WHY?
The roots of many plants spread over large areas quickly capture nutrients released by decaying plant and animal matter before the nutrients can be leached from the soil.
THEREFORE!
More nutrients are found in the living plants of the rainforest than in the supporting environment.
(1) What Is A Tropical Rainforest?
In general, a rainforest is a forested area that receives over 60 inches of rain per year.
1. Climate: High humidity is the main cause of high temperatures and the abundant rainfall.
2. Soil: Tropical rainforests grow in nutrient-poor soil and more nutrients are found in the living plants of the rainforest than in the supporting environment.
3. Location and
It would involve creating large dam-like structure extending from the coast straight to the ocean, with a perpendicular barrier at the far end, forming a large 'T' shape.
The plant is to open the existing dam to allow the circulation and exchange of water between the Lake Sihwa and the sea.
The tidal plant will improve the lake by circulating 60 billion tonnes of seawater annually
