Learning Task # 5. Matter Cycling within Ecosystems Label the diagram to complete the process and answer the guide questions on the paper required by your teacher. Guide Questions: 1. How does the flow of matter differ from the flow of energy through an ecosystem? 2. How do matter move through an ecosystem? 3. What do you think matter is used for?
Answers
1,The major flow of matter and of energy is that the flow of matter occurs in a cyclic manner i.e. it is recycled, however, the flow of energy in an ecosystem is unidirectional which means, it is not recycled. The flow of matter follows the following path-
A.Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants.
B.The nutrients pass to higher-level consumers when they eat lower-level consumers. When living things die, the cycle repeats.
C. In case of flow of energy, the energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
2.This loss of usable energy occurs because each energy transfer results in the dissipation of some energy into the environment as heat.
3.The cycling of matter in the ecosystem occurs through a series of food chains, food webs, and nutrient cycles. The matter is transferred from one organism to another as all of them are interconnected with each other.
A.It's used to build bodies. It's also needed to carry out the processes of life. Any nonliving matter that living things need is called a nutrient.
Explanation:
1.An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
2.Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.
- Matter, unlike energy, is regenerated in ecosystems. You can see how in the diagram below (Figure below). When decomposers break down dead organisms, they produce nutrients. Plants absorb the nutrients through their roots.
2)
- An ecosystem is a geographical area in which living or biotic elements such as plants, animals, and other species interact with abiotic or non-living elements such as weather, climate, landscape, water, and temperature to generate a stable community or a bubble of life. All of these elements are linked together via nutrition cycles and energy movement. They are an essential component of the biosphere.
- Natural and artificial ecosystems are the two types of ecosystems.
- There are two types of natural ecosystems: terrestrial and aquatic ecosystems. Freshwater and marine habitats are two different types of aquatic ecosystems. Based on their surrounding environment and climate, terrestrial ecosystems are divided into numerous categories.
- In the ecosystem, matter is cycled through a number of food chains.
3) It is used to construct bodies. It's also required to carry out life's functions. A nutrient is any nonliving matter that living creatures require.
