1. Organisms in most ecosystems form a complx network of interconnected food chains whih is referred to as a food web. Below is a food web which is explaining that solar energy from the sun goes to the ocean which is abosorbed by the Zooplankton, then transfers to the birds, from the bird it goes to the huvenile herring which is eaten by the whale. Or it solar energy is absorbed by the zooplanktonwhich is eaten by eaither a Capelin, polar cod or seal. Capelin then get eaten by the cod or he whale.

2. The type of net primary productivity in Sierra Leone is the forest vegitation type which is at the highest value. Most of the productivity in forest vegitation occurs during and following the wet and rainy season. The gross primary productivity in Sierra leone is Fringe Forest.. most at which are found along the fringe of shorelines.

3. Producers as we all know get their energy from the sun which is about 10,000 kilocalories. Producers are organisms such as plants,algae and aquatic plants. Herbivores are organisms that eat the plants to gain energy. Herbivores are primary consumers which are animals like rabbits,grasshoppers, deer ect. Carnivores are secondary consumers that eat meat and gain energy off the primary consumers. These are animals sch as spiders, birds, frgs ect. Omivores eat and get energy off both plants and animals. Humans, pigs, foxes and cockroaches are all considered omivores. Decomposer are consumers that release nutrients rom feedng off dead bodies of plants and animals. Deecomposers play a big role in returning the dead bodies to the soil,water and air to be reused by the producers.

4. Humans effect the nutrient cycles in many ways. Sierra leone is effecting the water cycle by poor solid waste managment,discharge of untreated indutrialize wastes and other waste issues. These waste issues are contaminating urban water supplies. The burning of fossil fuels is a way they effect the sulfer cycle. They effect carbon cycle by deforestation which means clearing the forest by burning or logging it. This damages habitat ans biodiversity while it also had a impact on adding cabon dioxide in to the atmosphere.

5. Yes there are some types of resaearch being used to study the ecosystem. There is reasearch being used such as national statanible Agriculture Develoment Plan which is as study team that use data and documentation on ecosystems. Toxonomic reasearch which is a reaserch used for primary food sources.
