Make a claim to answer the question, “is there a relationship between how Bob services the lawns, and the rate at which the lawn grows and the number of decomposers observed?
Look at the article/data to answer the question

Answers

Yes, there is a relationship because when he left the cut grass on the lawn it increased the amount of decomposes while where he remove the cut grass, he was able to see less decomposers and the length wasn’t as much as Lawn 1. In conclusion we can conclude that leaving the cut grass on the lawn just increased the average number of decomposers and increased the length of the grass.
Ecology (from Ancient Greek οἶκος (oîkos) 'house', and -λογία (-logía) 'study of')[A] is the study of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism.

Among other things, ecology is the study of:

The abundance, biomass, and distribution of organisms in the context of the environment
Life processes, interactions, and adaptations
The movement of materials and energy through living communities
The successional development of ecosystems
Cooperation, competition, and predation within and between species
Patterns of biodiversity and its effect on ecosystem processes

Ecology has practical applications in conservation biology, wetland management, natural resource management (agroecology, agriculture, forestry, agroforestry, fisheries, mining, tourism), urban planning (urban ecology), community health, economics, basic and applied science, and human social interaction (human ecology).

The word ecology (German: Ökologie) was coined in 1866 by the German scientist Ernst Haeckel. The science of ecology as we know it today began with a group of American botanists in the 1890s.[1] Evolutionary concepts relating to adaptation and natural selection are cornerstones of modern ecological theory.

identical twin? Imagine that you do! How do identical twins
happen? How do they have the same DNA?
LONG EXPLINATION

Answers

Explanation:

How do identical twins happen?

Answer: To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.

How do they have the same dna?

Answer: Identical twins (also called monozygotic twins) result from the fertilization of a single egg by a single sperm, with the fertilized egg then splitting into two. Identical twins share the same genomes and are always of the same sex.

Help with composting catastrophe

Answers

The term "composting catastrophe" refers to a situation where the process of composting, which aims to recycle organic materials into nutrient-rich soil, goes awry due to various factors, leading to undesirable outcomes and environmental issues.

Composting is an eco-friendly practice that involves the decomposition of organic waste materials, such as food scraps and yard trimmings, into compost—a valuable soil amendment. However, a composting catastrophe may occur when the composting process faces challenges that hinder its effectiveness and sustainability.
