That statement is true because The amount of energy at each trophic level decreases as it moves through an ecosystem at least is 10% of the energy at any traffic levels transferred to the next level the rest is lost largely through the metabolic process as heat.
Radial symmetry i think is the answer
Answer:
Explanation: Through time, there was a general trend towards the evolution of more complex multicellular algal forms there with specialized cell and tissue types but no further elaboration of the diploid life cycle stage.
For example
priming, subsequent diversification of indeterminate branched forms with leaves and roots.
The relative dominance of each phase shifted from the gametophyte (as in bryophytes) to the sporophyte (as in vascular plants) during evolution.
Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues.
