A wood louse belongs to the phylum Arthropoda.
Termites are considered primary consumers because they primarily feed on cellulose found in wood and plant material. As herbivores, they play a crucial role in breaking down organic matter and recycling nutrients within ecosystems. While they can be prey for secondary consumers, their primary role is that of a consumer that directly utilizes producers (plants).
Secondary xylem
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.
Examples of primary fuels - wood, coal Examples of secondary fuels - charcoal, coke
because wood is there food and home to live
it uses its antennae

The primary sector: - Raw materials, for example; wood, oil, metals, crops. The secondary sector: - Second in the production line mainly manufacturing items, making them and putting them together. For example: a wooden chair - The raw material; wood - Making the chair (In a factory)
The precambium is a layer of meristematic tissue found between the primary xylem and phloem in vascular plants. It is responsible for the production of secondary vascular tissue in the form of secondary xylem (wood) and secondary phloem.
Gymnosperms and dicots have secondary growth, which is the ability to grow in girth and produce wood. In contrast, monocots do not exhibit secondary growth and rely on primary growth for their development.
Secondary manufacturing refers to further processing of products that have already undergone some manufacturing. E.g. processing wood past its primary stage (e.g., lumber). Primary manufacturing is thus manufacturing of raw materials or materials in their near-natural state (e.g., iron ore, wood logs, ...)
